CYO SPORTS AT ST. THOMAS MORE SCHOOL

St. Thomas More participates in CYO Athletics, the Catholic Youth Organization league that brings together parochial schools throughout San Francisco, along with other private and independent schools and community groups. 

CYO provides students with a positive, faith-centered athletic experience that emphasizes teamwork, sportsmanship, discipline, and personal growth. Through healthy competition and shared values, our students build confidence, develop lifelong skills, and form meaningful friendships—making CYO a wonderful way for children to stay active while being part of a strong, supportive community.

REGISTRATION INFORMATION

Those new to CYO Sports will need to start an account with CYO's registration system called Team Sideline (TS) and enroll in a selected sport. If you already have a TS account, you need to enroll your child in the selected sport. 

​Lastly, if your child has recently transferred to STM and played CYO Sports for another program, please email Mr. Kavanagh, Athletic Director, [email protected], to inform him so that he can update the registration with CYO.  ​
