OSBA is volunteer-led. Parents stepping up as coaches, timekeepers, and scorekeepers is what keeps registration fees among the most affordable in the region.
Honoraria are a token of appreciation for the time head and assistant coaches give each season. OSBA also relies on parent volunteers each game for timekeeping and scorekeeping — please consider helping out even if you're not coaching.
