Since 1978 the Julian Krinsky School of Tennis has taken a comprehensive approach to improving young players' tennis games by focusing on fundamentals and strategy within a supportive, competitive environment. Krinsky himself is a former international tour player from South Africa who competed at Wimbledon and the French and Italian Opens.

Over the past 30 years, he and his staff of certified pros have taught tens of thousands of students. In summers, the overnight tennis camps for boys and girls take place at Haverford college and the Westtown School, while a special Krinsky Fitness, which includes C.O.R.E. Tennis as an option, takes place at Bryn Mawr College, all in suburban Philadelphia.

Students receive over five hours of individualized instruction and drills daily, reinforced by competitive play and supplemented by half-hour private lessons and cross-training sessions. There are also special programs for advanced and tournament players. All are supplemented by evening trips to the mall, the movies, historic Philadelphia sites, and the Philadelphia Zoo and weekend excursions to Baltimore, Dorney Park/Wildwater Kingdom, Great Adventure, Hershey Park, New York City, and elsewhere.
