Welcome to the Julian Krinsky School of Tennis (JKST) at Gulph Mills. Since 1978, we’ve been helping players of all ages and levels make dramatic improvements in their game by enhancing fundamentals, focusing on strategy and creating a competitive, supportive environment.

The Julian Krinsky School of Tennis was founded by Julian Krinsky, formerly a player on the international tennis circuit who competed at Wimbledon and the French Open. Now operated by Julian and business partner Adrian Castelli, the Julian Krinsky School of Tennis is a year-round academy with facilities in King of Prussia and Narberth, as well as world-renowned summer tennis programs at Haverford College, Bryn Mawr College, the University of Pennsylvania and the Westtown School.

Offering world-class instruction for players of every level, from beginner to serious tournament competitor, JKST tennis programs are directed by head professionals Gavin Siney and Arvind Aravindhan and taught by full-time USPTA-, USPTR- and JKST-trained teaching professionals. Our instructors use a comprehensive teaching method emphasizing stroke mechanics, footwork, strategy and competition skills to help you develop your game to its fullest.
