St. Isabella CYO offers basketball for boys and girls from 3rd grade to 8th grade.  4th through 8th grade players are entered into the Marin CYO league which offers an eight game season followed by playoffs.  Third grade players are invited to participate in our instructional course/league which is a mixture of  skills development and mixed league play.

CYO is an opportunity for all of us to learn and grow together.  Coaches are encouraged to play every player enough for every child to enjoy themselves, creating a better team and fostering community building.  If you want to join, click on the appropriate tab for more information.
