CONTRA COSTA COUNTY, Calif. (KRON) — Jake Hammerman is a varsity athlete on his high school’s tennis team, and he found a way to use the court for a good cause.

The teen and his team of growing instructors last year raised over $21,000 by offering $40 tennis lessons.

The proceeds are going to Meals on Wheels, helping feed Contra Costa County’s vulnerable residents.
