Cliff Drysdale, a 45-time Davis Cup veteran, is more than a familiar face in professional tennis—he's one of its signature voices as well, having spent more than 30 years commentating matches on ESPN. Students of his coaching system get to tap into that deep well of experience at In-Shape Sport clubs all across California. At each location, experienced tennis pros lead four-week clinics that cover the fundamentals of the sport, organize competitive leagues for more advanced players, and tailor lessons to teens. Additionally, tennis socials help guests practice the sport as they meet fellow players and use particularly ferocious serves to deliver their phone number to an opponent.
