In September 2012, JMTA expanded its geographic reach to SPORTIME locations in Westchester and on Long Island: SPORTIME Lake Isle, a state-of-the art 8-court facility in lower Westchester (Eastchester, New York); and SPORTIME Syosset in central Long Island, an 11-court facility that is SPORTIME's high-performance training.

Johnny Mac and JMTA Managing Director, Bennett Schlansky, have assembled a world-class team of directors including: Co-JMTA Directors Patrick McEnroe and Lawrence Kleger; JMTA Performance Director Richard-John Mensing, Jr.; JMTA Director of Mental Toughness and Performance, Dr. Dom Lausic, PhD; JMTA Director, Westchester Annex, JMTA Director, Long Island Annex, Michael Kossoff.

JMTA professionals work as a team to deliver a training program that will assure the best possible outcome for serious junior players; a program that will enable JMTA players to make the most of their abilities, while supporting them in their academic pursuits and in living balanced, healthy lives.
