GRETA’s Young Adult SOCIAL SUNDAYS are designed for young adults ages 21-39 to meet people and make new friends through the game of tennis. We offer a mix of fun games, challenges, drills, and matches. Our SUNDAY SOCIAL tennis leagues are social-first, with a hint of competition. Don’t worry if you’re just starting out or haven’t played since high school. We’re here to help you learn and enjoy the game of tennis!
