Advanced Tennis Clinic

Join Tennis Pro, Jonah Berkowitz, for a 90-minute advanced tennis clinic designed to crank up the intensity. Expect fast-paced rallies, smart shot selection, and plenty of variety—think topspin, slice, approach shots, and more. Instead of standard drills, you'll be hitting it out with other advanced players in dynamic, match-style play. It’s all about real-time strategy, high-level competition, and connecting with others who match your skill and passion for the game.

More about Pro: Jonah, a Dutchess County native, grew up hiking the Shawangunk Ridge and Catskill Mountains with his family. A former baseball player, he switched to tennis in middle school, inspired by the rivalry between Nadal and Federer. His passion for the sport led him to Montreal for the Rogers Cup and to the US Open as a ball boy for four years. By high school, he was competing in state championships and dominated the Mid-Hudson Athletic League, winning four consecutive singles titles and captaining his team.

Jonah also embraced pickleball, creating a court at his home and sharing the sport with his community. He studied neuroscience at Brown University, where he played club tennis and rowed on the varsity crew team. After graduating, Jonah won the Woodstock Open singles tournament in 2019 and worked as a tennis and pickleball pro at Woodstock Tennis Club and Zena Rec.

Now, Jonah enjoys cycling, learning languages, and exploring local bakeries. He’s excited to bring his love for tennis to INNESS!
