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

"I have nothing but praise for Gregg! I have been taking lessons from him for the past few years and my game has definitely improved.

Not only does he know his stuff, he is a patient and supportive teacher. I play mostly doubles these days and after taking some double clinics, I am a much better partner...I know where and how to move! Watch his videos...and learn a lot."

Linda Doty 4.0

I took Gregg’s lessons to gain more in-site on best practices in doubles play.

This program really helps prospective teammates develop winning strategies together. I’m all in with Gregg, his years of experience and his love of the game will make you a believer too."

Gene Chabot 4.5

"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.

"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

"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

"I came away from OTI’s weekend doubles clinic with a much improved doubles IQ.

The insights I gained and techniques I learned helped me gain confidence in my doubles game.

The individualized focus and personalized feedback from the instructors is outstanding. They were passionate about sharing their knowledge of the game and the experience far exceeded my expectations!"

Steve Mullis

"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

"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!"

What Students Say About OTI Clinics

"I'm feeling really good about my forehand since the clinic and I am seeing improvement especially with my serve.

Before our time together I had a few basic things I never really had clear in my mind particularly about what my body position should be at and right after contact.

You are right, watching the pros can be incredibly deceiving.

Now I understand, at least in my mind, what I should be doing in the stroke."

Alex Restrepo

"The clinics are great for all levels of players. It has given me a path for taking a shot I was already comfortable with (forehand) and turning it into a weapon.

My backhand is a much weaker shot - now I understand why and have a step-by-step process for making it better.

I really appreciate the practice routines that you learn because they don't require a hitting partner or even a tennis court.

I will definitely do more clinics in the future"

Kevin C.

"All I can say is ... oh my gosh! I have NEVER come home from any instructional/educational course (i.e. professional or personal) where I've felt so empowered and excited to apply what I learned immediately!

I've taken several three day professional clinics where I'm happy if I can take home even a few useful nuggets I can apply in my practice. I feel like there are hundreds of useful things I can apply from this past weekend which just blows me away.
Your ability to translate your knowledge to your students and your enthusiasm and passion is absolutely incredible and can't thank you enough for everything you've introduced me to this past weekend.

I realize it's still a long process and it's up to me to apply the lessons, but I'm confident that this OTI Clinic was exactly what I needed to kick start and reignite my passion for tennis and help me get to the next level in my game!"

David Y.

"I thoroughly enjoyed both days of the OTI clinic. Thank you! You're so good at what you do: superior teaching of technique, ability to break down the serve and forehand motions into easy-to-digest bits, caring so deeply about our progress, providing an instantaneous feedback loop, orally, visually, and through video, all the while making it a fun and productive learning environment.

To put it in simpler terms, you're a cool tennis nerd who knows how to teach :). I've started to implement what I've learned in the clinic into practice and matches.

Forehand balls are definitely heavier and more impactful. I'm also thrilled to know and understand now the proper serve motion.

Before I had no clue. While it still needs a lot of practice, my serve is way better than the push serve I had earlier.

My only regret is not taking your clinic earlier! 

Lisa B.

"I was somewhat hesitant about how much I could really improve in 6 hours and if it would be worth spending all the money to travel to this clinic but it ended up being the most valuable time I spent on a tennis court in a teaching environment so far!"
