John Letts

Owner, iTennis

A former Stanford All-American, U.S. Junior National Champion and ATP player and coach, John has been involved at the highest levels of tennis for over 40 years. After creating the largest tennis management company in Southern California with six facilities and thousands of students, John decided to turn his attention to creating the #1 academy in Southern California, founding the iTennis Performance Center in 2016. John’s dream is to recreate the magic of his junior development days, where at his home training ground, the Jack Kramer club, a small tight-knit community produced three #1 in the world players (Pete Sampras, Lindsay Davenport and Tracy Austin) as well as numerous top twenty ATP and WTA tour players (Derrick Rostagno, Kimberly Po, Eliot Teltscher and others).
