Girls Water Polo


League Champions '17, '18, '19, '20, '21

Program Philosophy

The sport of water polo requires fitness and dedication, and teaches the important values of hard work and team communication. In coaching our athletes to push themselves and build up their teammates, they'll learn to not only be better players, but absorb lessons and strength that come from pushing yourself. Whether success comes from on-the-field wins, or individual effort; teamwork, sportsmanship and discipline are the true measures of the program's success.
