What Students Say About Working With Gregg

"I was able to hit much better volleys than I ever had before! 

Now I’m really looking forward to going back and showing all my friends everything I’ve learned over the 2 days!"

Chris Constantini

"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

"II have had trouble with my backhand all my life. Not using the left arm, using it too much, too tight, too loose. Swinging across, not up. 

I went to OTI Instructor Gregg Le Sueur.
In a few short hours, he has systematically improved my painful backhand into something opponents will fear. 

I would recommend using OTI every day of the week. Thanks Gregg!!

Julie Dybendahl

"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.

"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!"

Alex Doman

If you have watched any of Gregg's videos, you already know how knowledgeable and effective he is in his presentations. His in-person sessions are even better. The facilities, coordination, follow-up, and even lunch are first-rate. Since I brought one of my fellow students to the course, I was gratified that he feels the same way about our investment in time and money.

I came late to the tennis game. Despite my fanaticism about my play, there were obvious big holes in my self-taught technique. Gregg identified them and had me on the road to stardom.
