REVIEWS

We Train Top Junior Athletes
— and Future Champions

From #1 USTA-ranked juniors to ATP/WTA prospects, GSET has helped shape high-performing athletes with long-term results.

I started at GSET when I was 10. I can easily say that GSET played a major role in my formation as a man. I learned not only the techniques I needed to play in a high level, but also Paulo and Gabriel taught me how to apply what I learned outside the court. I am extremely grateful for the opportunity I had to play for them and highly recommend it if you want to succeed. Cheers

With the philosophy that each child is unique, Coach Gabriel has developed a scientific approach to tailoring trainings for each student. He has an impeccable work ethic and leads by example by being prepared, prompt and positive, which makes him a perfect role model for young children (especially boys). Since taking lessons with Coach Gabriel, my children’s tennis game has progressed significantly. The connection between Coach Gabriel and my children is so strong that my children regard him as part of their life and a major motivation for becoming a better tennis player.

I’ve worked with coach Gabriel for over a year now. He helped me improve my performance and my WTA ranking by providing guidance in key areas such as technique, strategy, fitness and mental toughness. His lessons go beyond the tennis court. Truly grateful for an amazing coach!

What differentiates GSET's method from others is that training with coach Gabriel goes much beyond the court, it is an educational experience that helps the athlete in several aspects of life, be it academic or social. In the end, if you are looking to be the best, you have to train with the best!

My best tennis experience I've ever had! GSET has a totally innovative way of explaining tennis based on physical and biomechanical concepts! Today I am a first class tennis player because I had my tennis completely changed by GSET when I was 15/16 years old! I recommend this gym to everyone who really wants to learn quality tennis!

My 9 yr old daughter has been taking weekly private lessons for one month with Coach Gabriel and already we can see a noticeable difference in her form and confidence on the court! We can’t recommend GSET enough!
