HBO Bachelor Commercial Sports Economics
I have been a passionate athlete from an early age. As a child I fanatically practiced various sports, from swimming, judo and tennis to football and basketball. I soon discovered that basketball was what I enjoyed the most. I spent hours on the basketball court every day and every year I got better. As a youth player I was soon allowed to join the big boys, which greatly accelerated my growth as a player. I was selected for district selections and shortly afterwards for the National Youth Selection U16, U18, U20, U23 and the National Men’s Selection B. In addition to my top sports career, I studied Commercial Economics at the Johan Cruyff University of the Amsterdam University of Applied Sciences. Once I graduated, I continued to play basketball full-time for a number of years with great passion and enjoyment. After more than 10 years of being active at the highest level for the Eredivisie clubs of Amsterdam, Leeuwarden, Nijmegen and National Teams, I chose to focus on a social career.
Through a great project I ended up at Randstad, where I worked for five years in sales & recruitment in various departments. I combined this full-time job with a one-man business, with which I organized outdoor training for large groups. I enjoyed both jobs immensely, but my sporting heart beat the fastest. What I really wanted to do is help people become fitter and stronger, both physically and mentally, and inspire them to optimize their overall health. I made a career change and that’s how I got into the personal training profession. After attending many courses and seminars, at home and abroad, I have developed an in-depth and complete approach to helping people achieve their health and fitness goals. Growing my clients and improving their quality of life makes being a coach an incredibly rewarding job for me.

I am creative and ambitious, social, driven, and have a continuous urge to inspire others and help them become stronger.
Like everyone else, I like several things in life. But unlike many, I have been fortunate enough to earn a living doing multiple things throughout my career. Things I also liked.
I have worked a lot with music, worked in the catering industry for many years, and am seen as a guru when it comes to image editing. Whether it was the beats in music production, serving dishes during my work as Chef de Partie, or color schemes and pixel obsession in image editing – I have always had an eye and ear for details. I knew how to translate customer wishes into valuable advice and output. Skills that also come in handy in my work as a personal trainer.
To be honest, my love for sports and nutrition only came along later.
I used to play a lot of football, ice hockey and tennis at a young age, but that didn’t last. I only started looking into nutrition and exercise after I turned 30, seven years ago. A forced result of working overtime and not taking good care of myself. A recognizable story for many others who are going to delve further into health.
Because I made a lot of steps every day in the catering industry, I lost a lot of weight and had little energy. When I made a switch to healthy eating and started following a good training schedule, I quickly noticed that I started to feel fitter. Both physically and mentally. I had much more energy and better focus throughout the day.
Since then it has become part of my lifestyle. I can be found in the gym almost every day, love setting new goals, and try to take good care of myself when it comes to nutrition, mindset and balance. Fortunately, I can now also share that passion with others by helping them progress physically and mentally at RYS.

My journey in sports began as an amateur soccer player in my hometown during my teenage years, and it has been an integral part of my life ever since. Over the past decade, I have wholeheartedly devoted myself to a professional basketball career, encountering numerous exceptional coaches along the way who fueled my passion for strength training.
Upon concluding my professional athletic career, it seemed only natural to blend my academic background with the experience I’ve gained. In my work with clients, I consistently prioritize delivering the highest quality of service, continuously refining my skills under the guidance of world-renowned specialists.
I hold a degree in physiotherapy from the Eugeniusz Piasecki Academy of Physical Education in Poznań, Poland. The knowledge and insights gained there have greatly enriched my understanding of the complexities our bodies face in daily life, allowing me to approach them in a holistic and comprehensive manner. I firmly believe in the interconnectedness of the mind and body, recognizing that training both is crucial for achieving success in all aspects of life.
As a personal trainer, my objective is to empower my clients to unlock their full potential and become the best version of themselves. During our training sessions, you can trust that I will create the optimal environment for your development and select the most effective tools to accelerate your progress. I am deeply passionate about helping individuals achieve their goals and lead a healthy, fulfilling life.

Introduction to Self-Determination Theory: An Approach to Motivation, Development, and Wellness
My biggest passions are fitness and mindfulness. My intent is to fuse the two together and be a guide to clients on their mental and physical transformation journeys. To me, the goal of transformation is to become one’s absolute best self – and by challenging yourself mentally and physically in the studio, your personal growth can lead to an improved self outside of the studio as well.
Upon completing my Bachelors degree in Psychology and Film, I started my career working in the film industry in Los Angeles. I always loved being a part of creative industries, but knew that my heart was in fitness and coaching. Sports had always played a big role in my life. I did ballet and figure skating growing up, and as I began discovering my strengths in other physical activities, my passion for health and wellness only grew.
I am originally from Hungary and I grew up in the Netherlands, USA, and UK. I thrive in multicultural environments, which is why I feel at home in Amsterdam. My hope is that you will leave your training sessions feeling revitalized and stronger, both physically and mentally!

At RYS, we believe in the power of diverse expertise, and I’m proud to bring mine to the team. My journey began in a family deeply rooted in sports and wellness, which led me to represent Portugal in national basketball teams from U14 to U20. Competing at that level shaped my understanding of discipline, performance, and the mindset required to thrive.
After relocating to the Netherlands, I continued playing basketball at a semi-professional level while building a career in coaching, people management, and continuous improvement. In 2018, I reignited my passion for human performance, not just training the body, but understanding how movement, mindset, and recovery work together to elevate overall well-being. I began working intensively with Andrew Dawson, completing over 300 sessions that deepened my knowledge and sharpened my approach. That journey led to earning my Level 3 Personal Trainer certification and laid the foundation for the integrated coaching I now offer at RYS.
Since then, I’ve transitioned from freelance coaching to full-time dedication at RYS, where I help people transform not just their bodies, but their entire lifestyle. Our approach is holistic, integrating movement, nutrition, recovery, and mindset—tailored to each individual’s goals and circumstances.
🎓 Ongoing Education & Specializations
I’m committed to lifelong learning and currently pursuing advanced certifications to deepen my impact:
– Precision Nutrition Level 1 & Sleep, Stress Management & Recovery – PN Academy
– Functional Medicine – FMCA
– Menopause Coaching Specialist – GGS
These studies allow me to support people through life’s transitions, whether it’s managing stress, navigating hormonal changes, or optimizing recovery.
👨👧👧 Real-Life Experience, Real Results
As a father of four daughters, I understand the demands of everyday life. My coaching is grounded in empathy, science, and practical strategies that work. Whether you’re just starting your journey or looking to elevate your training, I’m here to guide you with clarity and care, to help you raise your standards and unlock your potential.
At RYS, we’re a team, each of us bringing something unique to the table. I’m grateful to work alongside Isabella, Krisztina, Leo, Paweł, and Andrew, and I’m excited to help you discover your next level.

Higher Education:
Personal Training qualification completed at North East Scotland College 2017/18
Achievements:
Applied Nutrition, Advanced Coaching Academy
My fitness journey started when I was six years old when my parents signed me up for figure skating lessons. This became my life as I competed around Scotland and the UK for 16 years. Workouts were always incorporated into my skating training sessions, so I started training in the gym at just 16 years old. Sports were my life, and I knew I wanted to be a personal trainer from a young age. I was born and raised in Scotland and I am half Spanish.
I have been a full time personal trainer since July 2018 and have worked with over 150 clients. I have gained lots of experience working with different types of clients over the years. My main specialty is fat loss and muscle building and have had many clients lose 20+ kilos in our time working together.
Personal training is extremely rewarding for me. I love seeing clients achieving their goals and seeing their confidence evolve as they gain strength and get into the best shape of their lives!
Currently, apart from training at RYS, I enjoy playing Padel tournaments, yoga, pilates and long walks. I still love to ice skate when I get the chance!

Currently in third year of Physiotherapy & Exercise Therapy at the Amsterdam University of Applied Sciences.
Achievements:
Milo Personal Trainer certification
My name is Quitino (Tino) de Kom (23), born in Paramaribo, Suriname. At the age of 18, after completing my HAVO diploma, I moved to the Netherlands on my own. I’ve now been living in Amsterdam for five years and am currently in my third year of Physiotherapy & Exercise Therapy at the Amsterdam University of Applied Sciences.
Sport has always been an important part of my life. In Suriname I competed in swimming and played football, and at the age of twelve I discovered the gym. From that moment on, I was hooked. What started as a hobby quickly grew into a true passion.
Driven by a desire to better understand training and the human body, I’ve had the opportunity to learn from various personal trainers in both Suriname and the Netherlands. Alongside my studies, I completed the Milo Personal Trainer certification and have now been working as a personal trainer for over a year.
My mission is to help people get to know their bodies better and make progress in a safe, enjoyable way. No quick fixes, but a thoughtful, step-by-step approach to building strength, conditioning, and confidence—always with attention to technique, safety, and long-term sustainability. I look forward to working together with you to build a stronger, more resilient body and mind at RYS.

My name is Błażej, and movement has been a central part of my life for as long as I can remember. From hip-hop dancing and skateboarding to competing as a professional basketball player, I’ve experienced a wide range of physical demands that shaped my understanding of performance, resilience, and body control.
As a coach, my mission is simple: to help you truly understand your body and learn how to control it with confidence. I don’t believe in chasing perfection — I believe in consistent progress, because that’s what leads to real, lasting results.
A quote that has always stayed with me comes from Socrates:
“It is a shame for a man to grow old without seeing the beauty and strength of which his body is capable.”
This philosophy sits at the core of how I coach and how I support clients in reaching their full potential.
My background as a professional athlete has given me a deep understanding of discipline, consistency, and the mindset required to achieve high-level results. My goal is to help you feel capable and strong in your own body — whether that means building muscle, reducing body fat, improving performance, or simply moving and feeling better in everyday life.
I hold a Bachelor’s degree in Physical Education, and after my professional basketball career, I continued to invest heavily in my development by attending courses and seminars led by world-class coaches working with elite athletes from organizations such as the NBA, NFL, Olympic teams, and UFC. This exposure allows me to combine proven training methods with a structured, results-driven approach tailored to each individual.
Fitness is not a sprint — it’s a long-term investment in your health and performance. Every program I design is carefully tailored to your current level, lifestyle, and goals, and evolves as you progress.
My mission is not only to improve your physique, but to help you Raise Your Standards — physically and mentally — every time we work together.
