Meet the Coach

Coach Reilly enters his tenth season heading both the boys and the girls tennis program.  He is assisted by long time JS coach Jack Ring.  Since taking over the duo has led the perennial power program to 10 consecutive  playoff appearances for the girls and 6 playoff appearances in 9 seasons with the boys.  In both 2019 and 2020 the girls won the VVAL title, going undefeated in league play while also winning the singles and doubles titles in the playoffs. In 2018, Justin-Siena had the number one and two finishers in MCAL singles play.  Prior to coaching at JS, Coach Reilly coached at Vintage High school for 6 seasons with the boys and 1 with the grils.  For more information about Justin-Siena tennis contact coach at
