I'm Stan Martherus — tennis coach and founder of Martherus Tennis Academy. I play at level 2 in the Netherlands and competed in college tennis in the United States, where I simultaneously completed my Bachelor's in Biomedical Sciences. I followed that with a Master's in Nutrition and Health.
Before founding MTA, I held a management role — an experience that sharpened how I lead, motivate and develop people. I don't just coach technique; I help players build the structure, discipline and mindset they need to keep improving.
My holistic approach is the result of years spent studying what actually makes a tennis player better. Sleep quality, nutrition, recovery, mental resilience, daily habits — these factors determine how fast you progress. Tennis is won long before you walk onto the court.
