Frederik is simply a fascinating personality. He has "gone through life" scientifically and can say something about every topic and every question. He is highly intelligent and yet packages the content in an appealing and engaging way. I recommend this coaching course to anyone who wants to understand themselves and others better and bring about positive change in the world. He clearly classifies the topics and distances himself from pseudo-scientific statements. He touches people where they need it. Do. It.

Frederik brings absolute clarity to every situation and every process. With an eye for every detail, the right questions and methods, real and sustainable change is possible. I really enjoyed trying out and learning all these skills. And at the same time to personally progress and grow with 7-mile boots. THANK YOU!

Frederik and his team, have taken me to my next personal level, without forcing a goal on you, but helping you to find and realize your personal goals. Thank you so much for this amazing journey over the last four months.

Experienced 100% effective coaching with Frederik and now learned it myself.

My second apprenticeship. The knowledge I had was deepened. I was able to gain an incredible amount of self-knowledge about myself and my situation. I had the feeling of being accompanied safely and extremely competently the whole time.

Knowledge that I was able to apply directly and immediately after the first module I had a new technique that I was able to use with my coaches and achieve amazing results.

5/5 stars.
A clear recommendation for anyone who really wants to achieve great results with their coachees and is interested in understanding themselves and their lives better and optimizing them during the training and achieving results that are sustainable.

Always happy to come back 🧡

Dr. Frederik Hümmeke and his team are quite simply the gold standard when it comes to neuroscience-based coaching and consulting work. Thank you for the great training The Coaching Leader and thank you for the many encounters during the training

The seminar was a complete success. Comprehensive, scientifically sound content, successful didactic teaching and perfect support from the whole team ensured that I was able to gain a lot of theoretical knowledge, practical experience and many insights about myself. In addition, there is an irreplaceable network with other participants and Vantisgo.

I am grateful for the great experiences and recommend everyone to take part in the seminar! Thank you Frederik and thank you dear Vantisgo team.

Thank you for the impetus to go on a journey...

Maximum scientific foundation paired with maximum practical benefit. At the end you are equipped with everything that makes you a competent coach and tools that are easy to use and almost bombproof.

I have now attended several seminars with Frederick. I am always impressed by the quality of his teaching and content. He manages to create a trusting space in which everyone can learn and open up.

Sebastian has been supporting me as an entrepreneur and our company for several years with clearly recognizable success. Whether in the context of closed meetings, management seminars, employee workshops or in personal sparring, Sebastian is a huge asset for everyone in our team and especially for me as an entrepreneur.

Without a doubt, he always has the necessary methodological tools with him, which he masters brilliantly, just like other successful coaches on the market. What Sebastian also brings to the table, however, is the incredible gift of picking people up, inspiring them, understanding them in depth, recognizing their talents and using them in a targeted manner. Thanks to Sebastian's support, we have succeeded in making entrepreneurial changes without leaving employees behind.

I am, and we are, very grateful for the journey with Sebastian. He enjoys our unreserved trust.
We are only at the beginning of the journey and look forward to the coming years with him and his team.

Sebastian Striewski has helped both our company and me personally enormously. His workshops have sustainably improved our team dynamics and efficiency. Personally, he helped me to define my goals more clearly and strengthen my skills. His empathetic and professional manner created an atmosphere of trust. His practical solutions and clear explanations are particularly valuable. Thanks to his support, I feel more self-confident and better prepared for upcoming challenges. I can recommend Sebastian to anyone looking for competent and motivating support.

From the very beginning, my experience with Dr. Sebastian Striewski has been a journey of inspiration and profound insights. As a coach and business consultant, he has a rare talent that tackles complex business challenges with impressive clarity and precision.

Dr. Striewski combines professional expertise with a human warmth that instantly inspires confidence. In every conversation, every consulting session, you not only feel understood, but also valued and motivated. He has a gift for breaking down complex issues into simple, comprehensible concepts that facilitate action and enrich daily practice.

His approach is characterized by a structured, goal-oriented methodology, which he always spices up with a pinch of humour. This combination makes the collaboration not only instructive, but also extremely enjoyable. Dr. Striewski is a master at getting the best out of everyone by responding individually and empathetically to their needs, whether in one-to-one sessions or in team settings.

His ability to act as an enabler for transformative change is particularly impressive. Under his guidance, I have learned not only to overcome challenges, but also to see and use them as opportunities. His advice has not only changed my view of my company, but also promoted my personal growth.

Dr. Striewski is more than a consultant; he is a true master of his craft, a beacon of wisdom in the often stormy seas of business life. Anyone who has the privilege of working with him is not only professionally enriched, but also humanly inspired.

The fact that we as a group of companies have been working together intensively and successfully for several years speaks for itself. Always highly professional and with a clear focus on results, without losing sight of the interpersonal component. Anyone who wants to make a positive and lasting change - whether on a personal or corporate level - is in good hands here.

Sebastian is an excellent coach and strategist who also recognizes the small things that need to be done and addresses them openly. Every project with him works and he knows how to pick people up and inspire them. After 12 months of working with him - thank you!

Works in the interests of his customers, drives his customers forward and allows them to think outside the box. A vision cannot be big enough to achieve its goals

He has been supporting me and our company as a consultant and coach for more than 4 years. Here I was able to get to know his excellent knowledge. In numerous sessions, alone and with my team, I have learned what it means to be a leader. For example, I was taught how to understand a team and the dynamics behind various statements. This was the only way I was able to resolve difficult moments in the team and thus create a positive atmosphere. I was able to experience his in-depth knowledge of psychology time and again using numerous examples. I was particularly impressed by his ability to convey complex concepts in a way that everyone involved, from the managing director to the journeyman, understood. Through his manner, he was always able to create an environment in which I and my employees could develop further. I can recommend him unreservedly as an expert and am very grateful for the valuable experience I have been able to gain over the years.

Sebastian Striewski has played a key role in our success. Without his expert advice and foresight, we would not be where we are today. His strategic insights, tireless commitment and dedication have helped our company to flourish and grow.

Thanks to his professional support, we have been able to overcome obstacles, seize opportunities and achieve our business goals at the highest level. His expertise, commitment to service excellence and dedication to our growth have made us a strong and successful organization.

We greatly appreciate working with him and recommend him without reservation. His contribution to our success is immeasurable and we look forward to a continued fruitful partnership to drive our business forward.

If anyone can take you from 0 to 10 out of 10, it's Sebastian. Whether it's dealing with stressors or achieving your goals. He doesn't dictate a path, but instead adapts to my individual needs and gets me where I want to be in a very short space of time. Anyone who is lucky enough to work with him has hit the jackpot.
