Our Approach
Structured, Game-Based Training

United OC Volleyball Club
Through a new collaboration between Orange County Volleyball Association (OCVA) and United Volleyball Club, OCVA has assumed operational leadership of the program in Orange County. As the first United franchise in the region, the program will operate as United OC under the management of OCVA. Previously structured as a for-profit organization, United OC will now operate as a nonprofit program aligned with OCVA's mission of making volleyball accessible to all athletes and families across the region.
Over the past several years, the program has established itself as one of the most successful clubs in Orange County, built on consistent performance, strong coaching, and a commitment to athlete development.
United OC is led by experienced coaches and former professional athletes who are dedicated to helping athletes reach their full potential. The program emphasizes consistent, high-quality training for every athlete, regardless of age or skill level, while fostering a team environment built on accountability, growth, and unity.
