Experiences from parents, players and coaches about our knowledge articles and method.
I tried three different tennis schools around Amsterdam before finding 359. The difference is night and day — structured lessons with a clear progression plan, not just hitting balls back and forth. My game has improved more in six months here than in two years elsewhere.

Expat — adult intermediate group
For over 10 years, we've been taking tennis lessons at 359.tennis and playing Saturday afternoon competition at TV De Kegel. We're a fun group of friends in the 50+ category. It's wonderful to be socially and athletically active together. The combination of lessons and competition truly keeps us together as a team.

As a family, we've been playing tennis with great enjoyment at 359.tennis for years. Two of our children follow the Academy and KNLTB Intake program, two are in the regular kids and juniors lessons. We also take group and private lessons ourselves. The training sessions are energetic, professional, and keep us feeling fit and vital.
