About
St. Sebastian Sebastopol CYO Basketball is a basketball program where players participate on organized teams during a defined season. Each team has one game per weekend, held on either Saturday or Sunday, and every team is guaranteed a minimum of one practice per week.
• Ages: 8–13 years old
• Schedule: Registration for the 2025/26 season opens August 1, assessments take place the last weekend of September, practices begin the first week of November 2025, games start the first week of December, the season runs ten weeks with a December holiday break and ends in February, and playoffs begin in March.
The program is open to any child in grades 3–8 who resides within a parish's boundaries. Practice schedules are set the third week of October and emailed by the coaches, with younger grades generally scheduled between 5:00–7:00 and older grades between 6:00–9:00. St. Sebastian CYO is in Sonoma County, with parish boundaries covering West Sonoma County and West Santa Rosa, and it is affiliated with St. Sebastian Catholic Church in Sebastopol. The St. Sebastian CYO program is part of the 12 parish North Bay CYO League, and during the season, scores and standings can be viewed weekly on the league website. The pastor is Rev. Mario Valencia.
The Catholic Diocese of Santa Rosa sponsors these sports activities as one dimension of its ministry to youth. The CYO programs seek to provide activities for all youth, encourage all players to participate to the best of their ability, and emphasize the team aspect of sports rather than “star” athletes and teams. Participants are taught to respect and affirm their teammates, and an atmosphere of sportsmanship, helpfulness, and patience is encouraged, while cheating, ridicule, and unsportsmanlike conduct are not tolerated. Failure in a game or in conduct is treated as a learning opportunity, and youth are challenged to do their best and to accept critique when appropriate; youth, parents, and coaches who are not “coachable” in their skills or attitudes may be asked not to participate. Teams are encouraged to try to win the game, but not at all costs, with sportsmanship, equal participation of all players, and fair play listed as the first priority of every practice and game. Players and coaches assemble at mid court before each game and read the CYO prayer. Adult volunteers are identified as key to the success of the CYO programs, and they are expected to be Christian witnesses, teach the fundamentals of the sport responsibly, treat each student fairly, and uphold the goals of the CYO program.
