Coach Dimas Acosta enters his fourth season with the Riverside Poly Volleyball Program, bringing a deep passion for the sport and a strong connection to the local volleyball community.

A native of the Corona/Riverside area, Coach Acosta began his volleyball journey in sixth grade through a local youth program, where he quickly earned recognition for his skill and leadership. He continued his development at La Sierra Academy, where he was a four-year letterman, two-time team MVP, Inland Coast League MVP, and was honored as the school’s Multi-Sport Senior Scholar Athlete MVP.
