The goal at Slim Tennis (‘Slim’ means ‘Smart’ in Dutch) is to make mental tennis training easy and concrete. Slim Tennis offers mental coaching sessions, webinars, high quality tennis lessons for developed players and a lot of reading material.

Tennis lessons for beginners
Tennis lessons for beginners are not a core product at Slim Tennis. Nonetheless, we saw an opportunity in stimulating tennis in Amsterdam, so we brought three parties together, namely:
- Triaz. A young tennis club in Amsterdam, where one can play all year round. Triaz also has the lowest membership fee in Amsterdam.
- William Higgins, a tennis-entrepreneur who recently moved to Amsterdam and still manages a large operation in community-based tennis lessons at schools and local courts across 3 cities in USA-California.
- Expats! Amsterdam has a large community of expats. Expats can now turn to Slim Tennis for flexible tennis lessons or just general information on tennis in the Netherlands. Read also more about our Expat Tennis Amsterdam (ETA) initiative!
Trainer/Manager – William Higgins

Location – Triaz
Tennis lessons are offered in Amsterdam on the location of Triaz (Van Heenvlietlaan 6 1083CL Amsterdam). Triaz is a ‘korfbal’ association with also five artificial grass tennis courts. The tennis courts are playable all year round. You get a discount to the Triaz membership if you sign up through Slim Tennis!
William moved to the Netherlands in August of 2019. He runs Higgins Tennis, Inc., one of the largest tennis lesson programs in the San Francisco Bay Area. He is originally from Austin, Texas where he was a top-ranked Open level player in the state. He played on the ATP tour after graduating from the University of Texas with an English degree. He ran the largest junior tennis facility in the world, the Barnes Junior Tennis Center in San Diego, and was the Head Pro at the Harbor Bay Club in Alameda. After moving to California in 2000, he was awarded the “Rookie Teaching Pro of the Year” by the Northern California United States Professional Tennis Association. In 2002, he coached Billie Jean King’s World Team Tennis Junior National Team to a National Championship in San Diego. He has worked with National Adult & Junior ranked players and teams.
William’s Offer
William’s goal is to set up a large tennis-lessons program at Triaz, including both private and group lessons. He works with players of all ages and abilities. Most importantly, he speaks English, Spanish, some German and French, and is learning Dutch! Expats will therefore feel right at home. Players of all ages and levels are welcome!
