Jack Stewart’s passion for tennis began when he picked up his first racket in middle school. During his four years spent playing the top position at #1 singles for his varsity high school team, Jack began coaching tennis as a volunteer at Urban Youth Tennis Foundation. This experience sparked and solidified his love for both playing and coaching, leading him to attend Ferris State University’s Professional Tennis Management Program and graduate with a USPTA Professional Certification. As the Head Tennis Pro at Crestmoor Community Association, Jack credits his own personal coaches for the inspiration. Today, Jack shares that same passion with players at the JCC.
