About The Clinic

OTI Instructors Gregg le Seuer and Fernando Martinez will be running this 1-Day serve clinic held in Flushing, NY on Friday, July 17th.

They will identify exactly which elements in your service motion that need to be fixed and they will fix them with you using the typical OTI progressive system.

All throughout the clinic, Gregg and Fernando will show you video of your serve and they will also compare you to top professional players on video, which will make it very clear what you need to work on!

The primary goal during the clinic is for you to add power to your serve and Gregg and Fernando know exactly how to do that.

What Students Say About Working With Gregg

"Changing your serve is challenging but Gregg's progressions made it very logical for me to improve my serve.
If you want to master a reliable and effective serve I would encourage you to work with Gregg"

Aaron Parker

"The doubles clinic was beyond my expectations!! I went in having told by my tennis mates that I have a pretty good volley and serve. They found multiple fundamental flaws.

I was amazed by their abilities to diagonise the root issues and suggesting the corrective technique and progressions and stressing with multiple repeatations and analogies the importance of correcting those.

Their voice over videos picked out the fundamentals once again ... the good as well as what needs to be worked upon. If you admit that you have some tennis "maladies" then go take a lesson with them ... I am not exaggerating ... I delayed for no good reason! ! Thank you to both of you!!"

Kris Saha

"My name is Lee Beneke and I am a 69 year old doubles player. I have never played the net, until I took lessons from Gregg, to learn how to volley and cover the net.

His instruction was amazing. The way he taught me enabled me to become an effective net player. I

 also took lessons from Gregg on doubles strategy. I’ve taken lessons from other teaching pros but I have never had anyone teach in a truly systematic way that honestly improved my net and my overall doubles game.

I feel very fortunate to have taken lessons from Gregg."

Lee Beneke 4.0

"I have been able to implement some of what I learned immediately into match play.

So in my world it would be called massive overwhelming value.

Thanks again and I know the party is at the net!"

Allen R.

"Gregg did a superb job getting our 2015 USTA 4.5 team ready for Florida sectionals. 

His tactical strategies, stroke improvements and correct court positioning helped us to go into the tournament as a strong, prepared team. 

Team members continue to work with him on their games and it shows by us going to sectionals again for July 2016. 

Our team agrees that Gregg is 'The Best' technical coach!!"



Michiele Conklin

"The OTI Serve Clinic is the real deal, do it! Gregg is a dream to work with and he corrected a serious elbow drop on my serve in just one session.

He has effective and easy-to-follow techniques for deprogramming bad habits and teaching proper mechanics.

I was impressed to see him tailor his approach to each student and achieve dramatically positive progression across the board.

On the spot video analysis is efficient. Everyone leaves the clinic with a plan for how to continue improvement.

Shane Donahue

"I am totally happy with the clinics! Of course they are in great locations and it's a great investment if you are looking for that in-person experience.

I highly recommend it to anybody who is out there - not neccessarily my opponents back home, but certailly my friends at the club and my USTA teams."

Jeff Walters 

"Gregg, thank you for spending the time teaching me last weekend.

I have attended several other camps in the past at well known big name academies and camps. 

Your clinics were, by far, the best I have attended and worth every penny. Your attention to detail and corrective actions were meticulous. If tennis players were given the option to choose only one tennis program, I would recommend yours!

Thanks again and I am looking forward to getting on the tennis court later today to practice!"

Ravi Ramaswami

"My 8.0 Mixed Dubs 40+ team from Seattle won the National Championships! 

 Was a crazy run. Serve and return have made great strides since working with you (and of course the forehand technique has come a long way.)

I'm into the men's 40+ 4.0 season and winning on the top court and my singles game is feeling strong also.

Hope all is well and thanks again for having a big impact in my tennis game!"

Peter G.

"In the past barely could I poach. Now I know where to go and when to go to poach. It feels natural, it works and best of all it's fun."

Betsey McKenna 3,5

"When I called my wife, she asked, knowing that I am a big fan of our local pro, "How does OTI in person compare with his clinics?" 

 I answered "I enjoy our pro's clinics and get a lot out of them. 

Still the disparity seems to me like the difference between attending a community college and studying at MIT"

Steve F.

"I rediscovered tennis after being away from the sport for 30 years. I have learned so much this weekend from Gregg and I will continue to learn and improve my strokes in the future.

I have learned more about tennis in two days than I have in the past four years through online videos and through other teaching pros. Thank you very much!"

Bill Collard

"You guys are awesome. Seriously, you far exceeded my already lofty expectations! 

It was the most amazing tennis instruction experience of my lifetime by a factor of at least 10! I am bragging about you guys in Atlanta! 

I practiced with a friend today. We played four 10 point breakers. I won two easily, where I've never come close before! He was flabbergasted at the improvement!"
