Great trainer, the course was a delight

Scrum Focus Class "Engaging the Brain" is highly recommended for every Scrum Master and Agile Coach interested in solving impediments and building their team. Mapping scrum artifacts to the SCARF model was fun and useful. It was a highly interactive course full of team exercises and certainly worth the while.

Super Introduction to Scrum

I recently completed a Professional Scrum Master (PSM) course and I'm delighted to say it was a super experience.
The facilitator, Gunther, was fantastic. His depth of knowledge on all things Scrum was immediately evident, and he was able to make the content genuinely interesting and engaging. He clearly has a passion for Scrum.
The course itself was well-structured and covered everything needed to build a solid understanding of the Scrum framework. I felt thoroughly prepared heading into the assessment, and I'm proud to say I passed on my first attempt! :)
I would wholeheartedly recommend doing a course with Gunther. Whether you're new to Scrum (like me!) or looking to formalise your existing knowledge (like others on my course!), his facilitation style makes the experience both enjoyable and highly effective.

Scrum Master class

I attended a two-day Scrum Master course and gained valuable new knowledge throughout the experience. I really appreciated the opportunity to collaborate closely with the other participants during the sessions. The course was highly interactive and engaging, which made it easy to stay focused the entire time. I would highly recommend taking this course.

Grateful for the insightful session by Gunther

It was a great and insightful session by Gunther. He gave time to discuss each and every question raised by us as participants and answered them thoughtfully. His deep experience and expertise were visible in every response, making the session truly enriching and engaging.
What stood out the most was his humility and openness to different perspectives. He didn’t just give answers — he sparked thinking, encouraged reflection, and made us feel heard.

The session felt more like a conversation than a lecture, and that made all the difference. It was a privilege to learn from someone who has contributed so much to the Agile community. I’m walking away with valuable insights, a fresh perspective, and a lot to reflect on.

Looking forward to more such meaningful learning opportunities!

Beyond the theory of Scrum

I have attended the first module from the Scrum Pocket Class about the Scrum Values by Gunther. The time spent in the group, the session structure, the insights and the group of participants that attracts is mind shifting in a really beneficial way. I can highly recommend it to anyone that already possess understanding about Scrum and want to go beyond the theory or as a preparation step towards PSM III.

Engaging and Insightful Scrum Values Workshop!

I attended the workshop "The Scrum Values (Module 1/2)," and it was incredibly insightful. Gunther facilitated it using an interesting case study and encouraged rich interactions among all the knowledgeable participants. The 3.5 hours flew by, and we gained tons of valuable insights. I can't wait for Module 2!

PSM-A with Gunther Verheyen

First of all, it was a pleasure and honour to have a PSM-A class with Gunther!
The class was well-organized and clearly structured.

Gunther did his best to answer our questions, provoke critical thinking about our knowledge of Scrum, and be very supportive when we struggled.

I highly recommend it if you're looking for a deep understanding of Scrum Framework.

Training with Gunther Verheyen

The training with Gunther Verheyen was absolutely fantastic! I gained an incredible amount of knowledge and a solid understanding of the fundamentals of Scrum. One of the most remarkable takeaways was realizing how we, as an organization, often overcomplicate things, preventing us from fully leveraging the power of Scrum. This training has inspired me to bring the lessons learned back to my team and focus on returning to the core principles of Scrum. Gunther is an outstanding trainer who masterfully holds your attention through engaging stories and practical assignments. His approach makes the concepts not only easy to understand but also exciting to implement.

Gunther's passion and wisdom are nice to see in action in one of his trainings around Scrum. In the PSM class he teaches, the stories he shares and the engagement he creates make it an interesting and invaluable experience, giving time to the learners to reflect on the topic for a better impact.

Pocket sessions to solve BIG problems

I knew this 'Scrum in the Large' session with Gunther Verheyen was going to be a good one when I booked it!
Starting with dependencies, Gunther peeled back the layers of the onion of scaling problems through interactive exercises. These exercises helped us develop a detailed appreciation of multi-team Scrum, laid out simply and elegantly in a way that we can use with our clients and get the focus back on the core, on what matters most; delivering value to our customers and stakeholders.
An afternoon of full engagement and interest with fellow practitioners!
I am super grateful to have had the opportunity to get some of my questions answered and misconceptions around scaling put to rest. I'm looking forward to sharing these nuggets with my clients!

Superb PO-A class with a Scrum Legend!

This is one of the rare instances where I feel, a five star review does not make justice to the experience provided by the great Gunther Verheyen. If you are looking for a knowledgeable and experienced figure in the Scrum and Product Ownership community who customizes the PO-A class according to his own insights and experiences, you should definitely go to Gunther. The classes are interactive and provide enough room for burning questions you might bring. One caveat of the PO-A class that is more a systemic caveat: It has a lot of materials but two days are not sufficient to cover all effectively. Thus, it is good to have such an experience trainer that can taylor and order the learn items according to the needs of the group. I sincerely recommend this class, and I would even take it twice - as it was such a great and refreshing experience.
