Perform with focus, confidence, and awareness β in the moment.
Technique. Tactics. Physical. Mindset.

Did you know most adults donβt get stuck because of a lack of talent β but because of mental noise in crucial moments?
During matches, rallies, and decisive points, itβs rarely technique alone that makes the difference. Itβs how you think, feel, and choose β while the game continues.
The Clinic helps you become stronger exactly there. On court, we work on your game β with attention to technique, tactics, and physical performance, and with a mental layer that is often missing in regular training.

INTRODUCTION
The Clinic for Adults
Β
Β
Are you ready to get more out of your game β in both training and competition?
The Master Your Mental Game β The Clinic is an intensive tennis clinic where all elements come together: technique, tactics, physical performance, and mindset.
During this clinic, we work on court on your game, with attention to what you do, how you do it, and how you handle it under pressure.
Not just training β but learning to apply it in match situations.
Itβs precisely there β where tension, decisions, and focus meet β that a small mental or tactical adjustment can make a big difference.
Β
During the clinic, you will work on:
Β» Technique β more efficient strokes, better timing, and conscious decision-making
Β» Tactics β playing smarter, recognizing patterns, and constructing points
Β» Physical performance β moving with intention, balance, and match intensity
Β» Mental skills β maintaining focus, recovering after mistakes, and staying calm under pressure
Β» Match behavior β handling tension, momentum shifts, and decisive moments
Everything we train is application-focused: so you donβt just understand it β you have the confidence and ability to execute when it truly matters.
Β
This clinic is suitable for:
Β» adult tennis players (recreational & competitive)
Β» players who want to elevate their game
Β» tennis players who notice that matches demand something different than training
Β» anyone who wants to develop more completely β technically, tactically, physically, and mentally
The Clinic is not just another training session β it is a deepening experience where my passion for tennis and mindset come together β practical, personal, and immediately applicable.
What do we cover during the clinic?
MODULE 1
Technique β building a reliable game
A match demands something different than a regular training session. In this module, we work on technique that holds up under pressure. You refine your strokes, timing, and footwork with one goal: more control, less doubt during rallies and matches. Not perfection β but reliability.
Β
You will develop:
β Technique that works when the pressure rises
β Better timing and shot selection during rallies
β Greater confidence in your fundamental strokes
β More efficient footwork for match situations
β Calmness in your technique β without forcing it
MODULE 2
Tactics β playing smarter, choosing better
In this module, you learn to read and control the game. Not hitting harder β but playing smarter. You work on patterns, positioning, and decision-making β so that during matches, you know what youβre doing and why.
Β
You will develop:
β Insight into tactical patterns and match situations
β Better decisions under pressure
β Game awareness: when to attack, when to construct the point
β Greater control over the flow of the rally
β Confidence built on clarity and direction
MODULE 3
Physical β energy, movement, and resilience
A strong game requires a body that supports it. In this module, we focus on movement quality, endurance, and recovery β tailored to match play. Not generic fitness training, but functional training for tennis.
Β
You will develop:
β More efficient movement on court
β Better conditioning and recovery during matches
β Greater stability and strength in your game
β Smarter energy management and load awareness
β The ability to stay sharp longer in points and games
MODULE 4
Mental β performing when it matters
The mental layer connects everything. In this module, you learn to handle pressure, mistakes, and tension β in the middle of the game. No long theory sessions, but practical mental cues that you apply immediately during matches.
Β
You will develop:
β Staying calm under pressure
β Recovering faster after mistakes
β Maintaining focus during decisive moments
β Playing from confidence instead of doubt
β More enjoyment and freedom in your game
This clinic is for you ifβ¦
Β
Β
β You know thereβs more in your game, but it doesnβt always show up in matches
β You make decisions under pressure that you later regret
β You notice that technique or tactics fade when the tension rises
β You donβt always stay physically sharp until the end of the match
β You are mentally affected by mistakes, pressure, or expectations
β You long for calm, clarity, and confidence in your game
Β
This doesnβt mean youβre weak. It means you are ready to consciously train your mental game. It doesnβt mean youβre falling short β it means youβre ready to train with purpose toward match performance β across every dimension of your game.
In this clinic, you work on technique, tactics, physical performance, and mindset β not as separate elements, but as they truly come together in competition. Not training harder. Training smarter. Playing more consciously.
Β
The result?
More control in matches.
Better decisions under pressure.
More energy, focus, and confidence β from the first point to the last.
Yes, this is truly possible.
Yes β Iβm ready to elevate my game.NICE TO MEET YOU
Iβm Bastiaan Kollen.
I grew up on the tennis court β playing, learning, making friends, and loving the game. Sport gave me joy, confidence, and discipline. But in my twenties, I discovered something just as powerful: the mindset behind performance.
I became fascinated by why some players freeze under pressure, while others rise above themselves. And I realized:
Β
Mindset makes the difference.
Β
Since then, Iβve dedicated my life to understanding the human mind β through NLP, psychology, coaching, and high-performance training.
Today, I help athletes, coaches, and professionals with the tools I once wished I had: confidence, emotional control, focus, and above all, enjoyment of the game.
Β
My mission is simple: To help people train their mind β so they can become the champion of their own game & life.
βCoach, isnβt everything just the story you tell yourself? If I tell myself Iβm old, Iβll feel old. But if I tell myself Iβm growing and that Iβm worthy, then I play that way too.β
β Taha
βThe mental coaching with Bastiaan was exactly the breakthrough my son needed β both on and off the court.β
β Rijker Fouwels
βThese workshops have been a true gamechanger for my sonβs tennis β and for his life.β
