Master Your
Mental Game

Master Your Mental Game helps you break through those blocks.
Whether you choose the online training, a workshop, an intensive clinic, private coaching, or the youth program: it’s always about the same thing — awakening your inner champion. 🎾🔥
Because when you change your inner world, your entire game changes… and so does your life.

Discover Your Path
I’m Bastiaan.
Most people know me as a tennis coach and mindset coach. But behind that label is someone with a deep passion for growth, freedom, and the art of living.
When I felt lost in my twenties, tennis brought me back to myself. It gave me direction, discipline, and fire. And that fire led me to psychology, NLP, and personal transformation.
In 2017, I began my journey as an A-level and B-level certified tennis coach. In the years that followed, I attended a High Performance Coaching Workshop at Roland Garros and grew into becoming an NLP Trainer. Throughout it all, psychology has remained the common thread — as a field of study, a practice, and a way of life.
I am a lifelong student.
Every year, I attend workshops, retreats, and programs — traveling to different countries to learn from coaches, trainers, and thinkers who inspire me. Not to preach one single truth, but to find the patterns that unite them — and translate what truly works into daily life and the court.
Today, I give that fire back — to you. 🎾🔥
So you can awaken your inner champion. Not just to perform better, but to live with more freedom, power, and joy.
💡 This is my invitation to Master Your Mental Game. So you can play fully. Live fully.

“The workshop helped me find more calm in my game. I no longer dwell too long on a lost point or a bad day. As a result, I play more consistently and with more enjoyment.”
Mapping out my growth areas (with the mental web) helps me accept mistakes as part of my development. I enjoy what’s going well more, and I can clearly see how much I’ve already grown.
At the start of a match, if things weren’t going well, I used to quickly think: this just isn’t my day. But thanks to Bastiaan’s insights, I can let that go and get back into my flow. It doesn’t work perfectly every time yet — but it’s already so much better.”
I feel joy, calm, and confidence in my game again. Thank you for that!

Nicole van Zuilen
Bastiaan’s workshop truly made me experience how powerful mindset is — on the court and in life.
His inspiring approach helped me become more aware of my thoughts, emotions, and behavior. I now actively apply positive thinking, growth mindset tools, and practical strategies such as worksheets and emotional anchors to stay focused and strong. The combination of theory and on-court exercises works brilliantly.
This journey has not only given me the tools to achieve my goals, but also to enjoy the process. I’ve learned to stay present, think in possibilities, and consciously choose the emotions I want to experience.
Truly transformational and highly recommended. Thank you, Bastiaan!
Elias Becker
My son Elias has attended several of Bastiaan’s workshops designed specifically for children. These trainings have truly been a game-changer for his tennis development.
Through simple yet powerful mental coaching techniques, Bastiaan has taught Elias how to better regulate his emotions and think more positively on the court. By applying practical tools such as setting small goals and creating personalized music playlists, my son has learned to take ownership of his thoughts and emotions — which has clearly improved his focus and performance.
What makes Bastiaan stand out is his ability to translate complex mental concepts into concrete, understandable steps for young athletes. This makes the workshops not only educational, but also fun.
Not only have Elias’ mental skills on the tennis court grown, he has also gained valuable life lessons that extend far beyond tennis.
Sean Maguire
Hi Bastiaan, just a quick note to let you know that after attending your courses, I achieved one of the goals on my “fridge bucket list” for 2022: I ran the Amsterdam Half Marathon!
The courses you delivered in Weesp last spring were definitely a key factor in making that happen — so thank you for that.
And as a bonus, I smashed my personal goal of running under 2 hours, finishing in 1:54:47.
Thank you for the positive impact your training and support have had on me. Truly valuable.
