Alexandru Gasca Silav

High Performance Hitting Partner - Touring Professional

Originally from Romania. I started playing tennis 5 days before I turned 11. By the time I was 14 I was a top 20 junior in my age division in Romania, just a few spots behind players like Wimbledon champion Horia Tecau, Wimbledon and Roland Garros semifinalist Florin Mergea, and former top 100 player Adrian Ungur.

I came to the U.S. at 19 years old and played college tennis division 1 for Nicholls State University for 4 years.

Currently 31 years young and for the past 6 years I have been training and competing at the professional futures level. I have the constant opportunity to practice, observe, chat and learn from, and be friends with many great players that are on the professional tour.

I am currently playing my best tennis at a high pro level and living my dream and passion to become the best tennis player that I can be.
