I help players develop the skills that actually make difference on the field - not tricks that only look impressive in practice. Every drill has a purpose and is designed to improve performance during real matches. My coaching focuses elite ball control, speed, agility, first touch, shooting, confidence and game intelligence, teaching players when and how to use each skill under pressure. 30 years of European soccer experience, i help players become more effective, more confident and stand out.

"My son John is 16 years old. English is not my first language, so I used a translator to write this review, but I really wanted to share our experience. I have known Tomas for many years because we used to play soccer together. Even back then, Tomas was always one of the players who stood out. Now, at 48 years old, he still has an impressive understanding of the game and the ability to demonstrate the techniques he teaches. When I found out he was visiting his family in the Czech Republic, I immediately called him and asked if he could help my son. My son plays in the Slavia Prague academy as a central midfielder, the same position Tomas used to play. At this level, competition is extremely high, and my son was fighting to earn a regular place in the starting eleven. We only had three weeks during Tomas’s visit, so we made the most of it—two days a week with two training sessions per day. It was very demanding and my son was definitely sore, but the improvement in his explosiveness, acceleration, agility, and overall dynamics was absolutely worth it. Another thing that makes Tomas different is his many years of experience playing high-level futsal. His ball touch, control, and quick footwork are something he can still demonstrate himself, not just explain. That made a huge impression on my son. Watching Tomas work with him reminded me why he always stood out as a player. He understands what happens on the field and knows how to transfer that knowledge to a young player. Writing this review is the minimum I can do to thank him. I truly hope Tomas can help many more young players the way he helped my son.

I help serious soccer players (ages 6–16) develop elite-level skills, game IQ, and physical performance. I’ve coached at youth, club, collegiate, and professional levels, working with athletes who want real results. My training is detailed, intense, and built around how players actually perform in games. If your child is committed to improving, I provide a clear plan, accountability, and measurable progress every session.

I bring a love of precise movement and competitive rhythm to coaching, guiding players to measurable improvement with clarity and patience. With 10 years' playing experience as a student and as a collage player I focus on stroke mechanics, tactics and match prep for all levels.

"I’ve been taking lessons with Poom for a while now, and the experience has been absolutely fantastic. As an older person, it can be incredibly frustrating trying to unlearn bad habits or figure out why a certain shot just isn't landing, but this guy has been a real gift for making the complex mechanics of tennis easy to understand. He doesn't just tell you what to do but he takes the time to explain why you are doing it, which has completely changed the way I approach my game. Within the first few sessions, he identified a few tiny tweaks in my footwork and racquet preparation that immediately added more power and consistency to my swings. He is incredibly patient and always knows exactly how to balance pushing me out of my comfort zone with keeping the sessions enjoyable. You definitely get an intense workout in, but you’re having so much fun hitting the ball and seeing real time improvement that you hardly even notice the fatigue. Beyond just the technical strokes, he has also been great at teaching match strategy and helping me build better mental focus during rallies. Whether you are a total beginner wanting to build a rock-solid foundation, or an experienced player looking to refine your technique and take your skills to the next level, I cannot recommend Poom highly enough. He is a truly dedicated coach who genuinely cares about his students' progress, and my confidence on the court has skyrocketed since we started working together.
