Meet the CordeValle Golf Dream Team
At the heart of CordeValle's golf experience is a talented team of professionals who bring together decades of experience, competitive achievement, teaching expertise, and a genuine passion for the game.
Jon Horner, Head Golf Professional; Chelso Barrett, Director of Instruction; and Joanne Lee, Assistant Golf Pro each bring a distinct perspective to the program, creating a well-rounded team dedicated to helping every golfer, from those picking up a club for the first time to accomplished competitive players, enjoy the game and reach their goals. Together, Jon, Chelso, and Joanne bring complementary strengths to CordeValle's golf program; leadership, competitive excellence, and a commitment to developing players at every level. Their expertise is reflected not only in the results they achieve themselves, but in the experiences they create for our members every day.
