About
St. Sebastian Sebastopol CYO Basketball is a youth basketball program where players take part in organized basketball practices, assessments, and league games. Each team has one game per weekend, held on either Saturday or Sunday, during the regular season.
• 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 with one game each weekend, 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. Every team is guaranteed a minimum of one practice per week, with younger grades generally scheduled between 5:00–7:00 and older grades between 6:00–9:00. Practice schedules are set the third week of October and emailed by the coaches. Players and coaches assemble at mid court before each game and read the CYO prayer.
St. Sebastian Sebastopol CYO Basketball is affiliated with St. Sebastian Catholic Church in Sebastopol and is part of the 12 parish North Bay CYO League. The Catholic Diocese of Santa Rosa sponsors these sports activities as one dimension of its ministry to youth. The program follows the CYO mission statement, which emphasizes teamwork, support, discipline, respect for teammates, sportsmanship, equal participation, and fair play, and states that cheating, ridicule, and unsportsmanlike conduct are not tolerated. The mission statement also notes that failure in a game or in conduct is treated as a learning opportunity, that youth, parents, and coaches who are not “coachable” may be asked not to participate, and that teams are encouraged to try to win but not at all costs. According to the mission statement, adult volunteers are considered key to the success of CYO programs and are expected to teach fundamentals responsibly, treat each student fairly, and uphold CYO goals. The pastor associated with the program is Rev. Mario Valencia.
