Don't miss out on our newest sport! Pickleball is one of the fastest growing sports in the nation and you don't want to miss out!

Our pickleball leagues are mainly for people new to pickleball, novices, and people just looking to hit the ball back and forth over the net. If you're a serious player, keep track of your player rating, or purposefully hit the ball between your legs, this is probably not the league for you.

Teams of 6 players (broken up into three mini-teams of 2) will play for one hour week on Sundays for 6 weeks of regular season games. Playoffs of up to 2 weeks for teams that qualify.

10.8, 10.15, 10.22, 10.29, 11.5, 11.12, 11.19, 12.3
