Duncan Maddox

Great course very informative and Interactive. The small er group also helped as it allows everyone a chance to speak and be involved with discussions. Duncan was very good at challenging ideas/comments making me really think about how to deal with real life situations as a Scrum Master.

Thank you, Duncan, for an outstanding and truly transformational training experience. Attending your Scrum.org PSM course was one of the best professional development decisions I’ve made. You’re not just a great coach—you’re a passionate Agile believer, a strategic consultant, and a thought leader who genuinely cares about helping others grow. Your ability to explain the Scrum framework in clear, simple terms, backed by real-world experience, made the learning both practical and inspiring. The small group format encouraged open discussion and deeper understanding. Most importantly, you helped me see not just what to learn, but why it matters, how to apply it, and how it can shape my career. You’ve shown me what it means to be an impactful leader, coach, teacher, and role model. Following your structured learning path, I passed the PSM assessment on my first attempt—even though the exam was tougher than expected. It was absolutely worth it. My manager had previously arranged a large-scale Scrum training with Duncan for our local council and strongly recommended him. Now I can confidently say: Duncan is one of the most inspiring and effective educators I’ve ever met. If you're serious about mastering Scrum and advancing your Agile career, this is the training you don’t want to miss.

Honestly, I'm so glad I signed up for Duncan's Professional Scrum Master course. I wasn't sure what to expect going in, but wow, it completely exceeded my expectations! What started as certification prep turned into this eye-opening journey through the Scrum framework that’s already starting to change how I approach projects.

 First off, Duncan is just fantastic. You know how some trainers can be a bit dry or overly formal? Not Duncan.He's got this amazing way of being super knowledgeable about Scrum while still feeling like someone you'd actually want to grab a coffee with. He made the whole thing feel relaxed and fun, even when we were diving into complex concepts. You could tell he genuinely wanted everyone to succeed, not just tick a box. The production quality deserves its own praise. The HD Zoom setup was incredible. Instead of squinting at a pixelated screen like most online trainings, it felt more like watching a really well-made YouTube video. It made such a difference in keeping me engaged and actually enjoying the learning process. One of the biggest bonus takeaways for me wasn’t even Scrum-related: 
Duncan’s facilitation is something else. While I came for Scrum certification prep, I feel like I also attended a masterclass in how to facilitate training and keep people engaged. I found myself taking mental notes the whole time, thinking, “I need to steal some of these techniques for my own workshops!” 
If you’re worried about two days being too much to handle - don’t be. The course was so thoughtfully structured, with plenty of breaks to keep our energy and focus high, even toward the end of the day. I genuinely wish my uni lecturers had been anything like Duncan! The pacing was perfect, and with the regular breaks, it never felt like a screen-time marathon. By the final day, I was surprised at how much we’d covered without ever feeling overwhelmed. Would I take another course with Duncan? In a heartbeat. Am I recommending this to my colleagues? Already have! And I definitely think this course is worth every penny. 

 I didn’t just learn how to pass a test but actually built real skills I know I will use every day. Thanks again Duncan!

Duncan is a very engaging trainer and uses interactive exercises to get the key points across.

Duncan is a very approachable teacher. Class is highly interactive and learned theory is always applied to real problems.

The class was really engaging and I enjoyed learning the content

Duncan the trainer was absolutely fantastic. He spoke eloquently and covered the topics well as outlined in the scrum guide during the session.. The class was interactive and people asked questions as it went along, with Duncan happy to clarify things. Overall he did an excellent job.

Duncan made everyone feel comfortable within the team. Material was very interactive within the meet but also in breakout rooms to apply learning. Duncan has masses of Scrum/Agile knowledge to translate to members to enhance their Scrum knowledge and techniques within their teams.

Duncan Maddox was very knowledgeable, professional, and personable. He created a welcoming, inclusive environment and made sure everyone was engaged and understood the content of the course. Thanks Duncan!

It was propably one of the more enjoyable courses I have attended in a long time. I have found the 2 days to be very informative and even though provoking and really helped me to understand the role of the Scrum Master

I want to extend my heartfelt thanks to my teacher Duncan for his amazing teaching and the incredible experience he offered in his classes. They were truly reviving and uplifting. Thanks to his guidance, I passed my exam with a very high score! Highly recommend his classes!

Had a very good experience on this course. Duncan made the content interesting and involved everyone. It wasn't a case of reading from a manual, it was practical, inclusive and interesting, which is always the best way to learn.

Thanks a lot for your wonderful coaching to understand the Scrum it really helped me a lot in the exam to apply the understanding in the exam questions. After the coaching Duncan replied to all my clarifications and queries and he sent reminder email to take up our first attempt which motivated me to do my first attempt and passed with 90%

I have now taken both an online Scrum Master Course and in person Product Owner class and succesfully passed the online assesments. I put the success down to: Materials: These really are top quality and having them provided after the courses is great as it means there is not need to keep jotting things down during and you can fully engage with the material Practicals: I learn best from doing, and the split between the learning via the slides and the practical excercises was just right. I have now omplemented some of the practices in my day to day. Teacher: Duncan Maddox took both classes and i can not praise him enough. His knowledge is top tier, he is engaging and I found his insight and recomendations on how to approach the assesment, including mock exams, helpful and a key to my success in passing. Highly recommend the courses!

Great teacher with a calm demeanor. Shows great knowledge about the topics at hand.

I recently attended a two-day virtual training which was led by Duncan Maddox for PSPO 1 certification. The two days were extremely well planned by Duncan in terms of topics to be covered, quizzes, group activities and mock assessments. Given the PSPO assessment can be tricky with the high qualifying %, Duncan ensured that we were aware of the kind of questions that may come, how to tackle situation-based questions and how to prepare well to clear the assessment. Duncan’s method of teaching was extremely good as the two days dint feel like a drag given, we were all attending the sessions remotely. He kept the classes interactive and engaging. I am extremely happy and satisfied with the quality study materials which were provided for a quick revision before the assessment. Thank You Duncan for being a great trainer and going beyond the two days to help and provide much needed inputs.

Interactive, collaborative, and engaging. Many lightbulb moments to takeaway from the course. Duncan is an amazing trainer who kept us all engaged despite the late hours due to time zone difference. The training materials and format made it very easy to collaborate. Good classroom size.

I have attended 3 of Duncan's classes so far, so definitely he is doing something good if I returned... He makes the theory easy to understand through interactive, thought provoking, relevant exercises - a catalyst for personal and professional growth!

Great course with a lot of interaction a simple method of transmitting the knowlegde.

Interactive & thought provoking sessions with coach Duncan Maddox, working at a range of paces throughout the course. Good direction from coach. Variety of activities. All my suggestions were considered. Safe space for interactions. Excellent exam support was offered alongside clear directions for participating in the course. I followed the instructions and passed first time!

Great structure and relevant exercises/scenarios throughout the course. Good sense of pacing and amount of breaks that allowed us to regain our focus between exercises. Felt encouraged to ask questions throughout the course which were also followed up with relevant discussions back and forth. Do recommend!

Our APAC team had a 4x half-days PSM I training with Duncan as he adapted the training format to suit our different timezones. He is obviously very knowledgeable, and is very nice to speak with. I spent a very good time in the sessions, as the pace and atmosphere were enjoyable, the content was great and well-presented using Miro, and Duncan really highlighted the important information. Summary emails, access to online class resources, and additional tips made me feel confident that I had all information needed to finalise preparation and attempt the assessment. Thank you Duncan!

Interesting course content, engaging and knowledgeable trainer

Duncan lead an excellent training. Very engaging and informative.

Duncan was a great teacher and made the course informative and enjoyable

My experience of the course was excellent. It was engaging, fun and offered a genuine collective learning experience. I have numerous years of experience practicing scrum, but this course is a real eye-opener.

Great training as always - lots of great conversations and exercises

Very detailed course with lots of examples and exercises that was helpful to understand Scrum framework. Instructor Duncan Maddox was very helpful and skilled and we had interesting discussions in the class, driven by a instructor with lots of experience in Scrum use.

Duncan was a great trainer and really made the material relevant and very interesting, highly recommended course and trainer.

I've just passed my PSM I certification exam thanks to this class. Duncan did a great job explaining the fundamentals of Scrum and the skills needed to succeed as a Scrum Master. He fostered a sense of camaraderie among the class participants and offered thoughtful group exercises that helped demonstrate key concepts of Scrum. If I had some constructive feedback, it would be that Duncan doesn't allow much time to complete some of the exercises/quizzes, but it seems that is also key to exploring some of the real world problems encountered in the role.

Duncan has a wealth of expertise and really took his time to simplify things by using real life scenarios alongside the Scrum framework. The course overall is very interactive and the breakout room sessions were very helpful as it got us all thinking and applying our knowledge as we went along. Would 100% recommend the class to get you prepped for the PSM I exam.

The way of share knowledge, the time dedicated, the effort...the course went really well. Fully recommended

Lots of facilitation tools to utilise in real time scrum events- great exercises very interactive

Duncan made the class very interactive and fun. Participation was key and it was the best way to learn!

I am happy with the way Duncan communicate with the participants and conducts the two days training. During the training the topics were introduced in an easy way to understand and recognize the real value. Simple examples were presented and some exercises with other participants helps to fix the content of Scrum Guide. At the end, Duncan shared relevant recommendations and guidance for the Scrum Assessment.

Plenty of collaboration exercises in small groups, regular breaks, good explanations and well picked real world examples to illustrate the different concepts.

This class was so informative and very well presented. The Instructor kept the class engaged. I learnt a lot and thoroughly enjoyed it. Looking forward to doing another.

Do you know those courses where you are so bored you can't wait for them to finish? This is not one of them. Duncan is incredibly knowledgeable in the matter and accomplished to make the two-day course very engaging, thought-provoking, and enjoyable. Topped with a sprinkle of funny bits that made the experience a brilliant time investment: I got a 100% on my first try! Definitely would attend more of these if all instructors were like Duncan.

Duncan is awesome! I have been to a few training courses with Duncan and he is amazing! He can make complicated theories easy to understand by introducing engaging practise and little stories. I would recommend the courses with him.

Excellent well planned Video session. I throughly enjoyed the session especially in the breakout rooms we were grouped differently every time. That way we got chance to learn from one another. Duncan our course facilitator explained every modules clearly.

Really good trainer; very knowledgable and great real-world examples to help adopt the newfound knowledge.

Well structured and informative. Was fun. Though the time we had during each exercise was quite short, so I would suggest to either add more time given to each exercise, or have fewer but longer exercises.

In-depth knowledge of the tutor made this course easy to understand

I could not have asked for a more engaging, fun and intriguing virtual classroom experience. Duncan was a great coach, he was patient and provided a great foundation for taking and passing the PSM I assessment. I would certainly recommend for anyone considering taking the assessment or just learning more about scrum and its application in the real world!

Duncan was very knowledgeable, he explained everything in a very clear way with real life experience relating to the projects he worked on. At the beginning of the training I was not clear on few concepts, but at the end it was clear.

Duncan is an excellent trainer and keeps you engaged throughout the whole time. His personal experiences are vast so he can easily tailor real world examples to make them relatable with you. He does a great mix of group discussions and breakout rooms. His passion for Scrum comes across in the courses I have been on with him and I would seek him out for future courses.

The class was informative and precise about Scrum theory and practice. Duncan set an excellent formula to keep you interested and cover all the topics by providing excellent examples and exercises. He gives you everything you need to understand the framework and to prepare you to pass your assessment successfully.

Clear concise explanations, very knowledgeable about scrum as a framework and real world problems

Duncan Maddox is an excellent, very engaging trainer who kept us on our toes at all times. During the two day course, there were numerous exercises to tackle problems with others in breakout rooms, which reinforced our learning.

Duncan was a great teacher and kept us interested throughout the course with real life examples and enough breaks to keep us lively! He also gave great advice on the exam, which I've just taken and got 100% in. Thank you Duncan for all your tips and advice :-)

Amazing experience gained for 2 days training led by a great open trainer Duncan Maddox. I would be definitely happy to work with Duncan again and highly recommend him as a top-notch trainer and a nice person.

The trainer created a great container for the course where all participants could be at their best.

It was really exciting and useful class. Duncan was working hard during the class to dive us into Scrum practice. It wasn't just boring theory but a lot of exercises for practice skills development. More over I'm using gained knowledge to improve processes in the my team now and already started implementing of Scrum framework... I didn't expect such result. I was a bit sceptical on the beginning but it the end it was really hard to say "Bye" to Duncan and all group.

Great training, I came away with a lot of insight and ideas I'm keen to implement. I highly recommend. Thank you Duncan.

Engaging and constructive learning experience. Structured content with theory and practical application led to immediate thoughts about ways to adopt this into current work. Duncan was a brilliant instructor and always invited open discussion with positive and encouraging feedback.

The sessions were very interactive with real life scenarios to discuss and debate.

Really nice teacher, knows his stuff and is also very entertaining and engaging.

Duncan is the best!

Excellent facilitator guided us through a well-structured training material. Highly recommended course for PSPO.

great class very informative

excellent, collaborative, interactive, easier to understand

The PSPO 1 training was great. I've learned a lot and the the way Duncan taught the group and material was super good and interactive.

Duncam is a well experienced trainer in scrum and conducted the training program with utmost proffessionalism and also kept all of them engaged.

Highly appreciate an interactive and participant centered session to collaborate more minds on agile methodology. Concise presentation on roles & responsibilities of Scrum Team. Duncan stated real life examples/challenges organization face and guidance on principles/recommendation to overcome Scrum inefficiencies.

Very interactive and engaged environment to learn.

This course helped me to understand in details of Scrum running within an organization. This course is very valuable and gives us an in depth knowledge with a perfect coach as we had one and very grateful for the same.

Duncan was great in explaining how scrum works in a very clear and coherent manner.

Excellent instructor, useful content

Challenging, thought-provoking, motivating and really enjoyable.

Excellent course, well presented and with plenty of discussion.

Duncan is a fantastic trainer. He runs a clearly laid out course with great slides and the classes are highly interactive using zoom, a MIRO board and breakout sessions for exercises. He questions rather than tells, forcing you to think, which makes the lessons sink in much better. He's more than happy to answer questions, has great industry insights and fosters a fear-free, open and engaging classroom environment :-)

The class was great. I leant a lot and the exercises kept the material interesting and fun to work with Duncan has a lot of energy and was open to questions and discussion. The example questions were useful to help check my understanding.

I would like to take the opportunity to thank Duncan for delivering a very engaging 2 day session. The course is structured around exercises which helped me get a better understanding of how a PO is meant to operate. This links up with all the theory that we went through and has prepared for future PO roles.

I've Taken Duncans Classes for both PSM I and PSM II and have found them to be highly insighful, not only for passing the exams but in gaining a deeper understanding of Scrum and application to my current work.

Thoroughly enjoyed this course, very interactive and well lead by Duncan. Having no previous experience of Scrum, I was able to pass the assessment first time with confidence. Highly recommended.

Very nice moments sharing with Duncan and the mate from the class. Good conversations for improving Professional Scrum Master skills. I strongly recommend the course to people who want to go deep inside professional Scrum Mastering, Liberating Structure tools, wonders how to deal with conflict situations and want to share their concerns regarding their daily work.

Duncan really knows his stuff! A passionate Scrum Trainer who is always happy to go the extra mile to give students better understanding and answer any questions; even after the course was delivered. Truly the best Scrum trainer I've come across to date. Recommended for any prospective PSM and has inspired me down the path of trainer myself. Duncan will get you through the exam and will answer any questions you have in relation to integrating Scrum in your Org.

Duncan maintained an inspiring and engaging classroom that not only prepared us extremely well for the professional scrum master 1 exam, but also provided us with effective answers and professional recommendations to a huge variety of questions when it came to how we might use the course materials to apply professional scrum in our individual organisations.

Taking the PSM II class with Duncan makes you a better leader. While taking the class, I have learned a lot about being the leader who serves, and while improving my Scrum knowledge I was also able to emphasize my skills on enabling teams and making them selfógranized. A challenge I have encountered many times in my career. I'm an engineering manager, in an environment, where there is no Scrum, but something the company calls Scrum, and where there is no Scrum Master. However, I believe that the values of Scrum can benefit my team and the company. In Duncan's course, I felt most intriguing the way he conveyed the information. Facilitation, Liberating structures, training from the back of the room. It was enlightening to see how to make a group engage with each other, who had never seen themselves before, came from different places in Europe, and who still was able to be very engaged in the exchange of wisdom.

The PSM course that we did with Duncan was absolutely brilliant. He was a great instructor, explained things really clearly and was also very patient with us. Not only do we all feel confident to take the exam, we also feel so positive towards changing things up in our studio. If we ever want to take any further Scrum courses in the future, we would definitely choose to go with Duncan again.

It was a great experience. Duncan is a very knowledgeable teacher who answered all of our questions and focused on keeping everyone engaged. I was very happy that the class was face to face as I think that's the best way to stayed engaged. I have done several online courses on Agile and Scrum but none of them left the subject as clear as a face to face class with a teacher.

Really honed in on the content l learnt during PSM I. I'd recommended this course for anyone wanting to deepen their understand when using SCRUM for complex projects.

Excellent training, good support document and really good support in general. Thanks Duncan

An interesting Group course with good interaction. As Agile is a very new experience for me personally, it was good to complete the course with other colleagues who are already using Agile. In my current Role of resolving Quality / Warranty Problems, we already use a recognised 8D problem solving methodology. I feel that I have an advantage of applying Agile to the 8D process. It will help in Attention to detail and verifying the True and accurate Root Causes to the problems.

Excellent tutor, great supporting slides. Engaging and enjoyable

Duncan is a great instructor and I really enjoyed his course.

The classroom was an excellent learning environment. The use of Miro was good, the examples were clear and the interaction was very open and honest from both participants and the course leader. The course leader was clear in his delivery and it was evident that he had experience in the topic he was teaching. The material used was clear, well put together and very easy to follow Overall I cannot recommend the course and the course leader enough.

After passing the assessment on the first attempt, I'm confident to recommend Duncan to my colleagues. The time of the two day training and an extra hour session was well spent. Duncan is a fun and knowledgeable trainer and there were different kinds of learning methods used during the course therefore it was easy to stay engaged and focused. I followed the trainer's advice on how to get ready for the assessment and it worked.

Great structure, good pace, excellent time keeping. Clear communication, great trainer. Thank You for the good experience

Really insightful course related to the scrum principles and theory and how the team operates.

Ive taken 2 courses with Duncan and both times I've been so happy with his expertise and fun, charismatic teaching style. I highly recommend him.

Really enjoyable course

It was a great learning experience. Duncan was knowledgeable and made the 2 day learning sessions fun and interactive. Lot of interactive exercises helped us to understand the concepts better.

Really clear and useful structure with many interactive breakout sessions! helping to learn by doing was rather effective. course content was well laid out and Duncan always answered all queries.

excellent informative class with lots of humour and interaction, made course engaging , huge thanks to Duncan who not only taught us exceptionally well but kept it light and provided excellent support..

would prefer to be back face to face, but the world being what it is, this is the best we can do.

Definitely the most professionally put together and well-executed training course I've done to date - Duncan was superb.

Duncan had the experience and the personality to delivery a great course. Took the team though practical examples and also challenged the thinking with a warm blooded mammal burger. Highly recommend this class and Duncan as a trainer.

Great informative and interactive class. Duncan keeps everyone engaged and on their toes :)

I would like to express gratitude and appreciation towards Duncan, as he was phenomenal and very enthusiastic and encouraging with his words. I came in with somewhat knowledge of the topic, but with his guidance and links to mock assessments, I was able to grasp even deeper understanding of Scrum principles. Thank you, Duncan. These two days were truly a delight.
