Eight indoor hard courts. Fifteen elite teaching pros — including a former ATP player, a USTA tournament director, and a PTR-certified coach with three decades on these courts. The training ground for nineteen New Jersey state singles champions and more than six hundred USTA nationally ranked juniors.
John Costanzo built this program from one notion: unfussy, traditional, and obsessed with what wins matches — grips, footwork, stroke development, time on court against players who push you. Three decades later, that notion still runs every clinic, every private, every level of the junior pathway.
Six hundred USTA nationally ranked juniors. Five state champions with his name as the first listing on their college recruiting profile. He answers the phone at the front desk most mornings.

Members, parents, and alumni — what they actually say about training at GSTC, in their own words.
My son trains here three days a week. He went from a 3.5 ranking to a 4.5 in eighteen months. The pros pay attention.
Came in as a complete beginner at forty-two. They put me in Gordiy's clinic and I'm playing competitive doubles a year later.
When I was being recruited, three different college coaches asked where I trained. Garden State did more for my game than any clinic I went to.
