Tennis courts at sundown

Jon Griesser

Certified Tennis Instructor • Private & Semi-Private Lessons • All Levels
Tennis instructor, lifelong player, and founder of 10SLIFE — helping players of every level fall in love with the game and play their best tennis.
10SLIFE started on the court. After years of coaching players from first-timers to tournament competitors, Jon set out to build something that captures what the game really is — not just a sport, but a lifestyle. On the coaching side, Jon offers private and semi-private lessons tailored to your level and goals: fundamentals, footwork, stroke mechanics, strategy, and match play. Every session is hands-on, encouraging, and built around helping you improve fast while having fun. On the apparel side, 10SLIFE is premium tennis gear designed by a player, for players — comfortable, durable, and made to be worn on and off the court. Gear up, book a lesson, and live the 10S life.
