Client Reviews of Matt Seideman

I wanted to better my game for league tennis at Stoneridge. Since I have used Matt for instruction I have been able to break down my swing and  correct my errors, better my volley, learn strategies, develop a new serve, and win nearly every match the last 2 seasons.......I'd say that's pretty good!!!!
I'd definitely rate Matt a 5 out 5. Thanks Matt

Client Reviews of Ralph Acosta
In the 7 lessons I have had, I have dramatically improved my serve and can hit a decent backhand with topspin
(a shot that has eluded me up to now).
The way Ralph teaches is amazing as he tailors his teaching methods to each student and explains the physics behind the genesis of good shots. Also he gives amazing images to help one out. Whenever I had a “block” he came up with amazing tips and I see immediate results. He's the finest coach I've seen in 59 years and I have trained with many. It's been a privilege to have found you and the hour lesson feels like 5 minutes!!
