FIT High Performance Tennis Academy & Pickleball Center operates in Windcrest (San Antonio), run by owner Michael Castello with instructors coaching both a competitive junior tennis pipeline and a growing pickleball program under the FIT Pickleball Fitness Center banner. The pickleball side runs outdoor concrete courts with a $7 day-entry fee, open play, and a challenge-court format for all levels. Hours split around the tennis academy’s after-school programming: weekdays roughly 8:30 AM to noon and 4 to 9 PM, Saturday 8:30 to 5, Sunday 8:30 to 1. The broader academy runs speed-and-power training, summer camps, private lessons, and has produced tournament-winning junior players across USTA events.
