When she’s not collecting Grand Slam titles and awing us with her athletic prowess on the court, Serena Williams is giving back.

Earlier this week, Williams went to Jamaica to help build a school. Williams’s SW Fund charity teamed up with Helping Hands Jamaica to build the Salt Marsh Primary School.

Salt Marsh is the third school that Williams has built through the SW Fund, a charity founded by the elite athlete that “individuals or communities effected by senseless violence, and [ensure] equal access to education.”

Williams shared pictures and videos of her and her fellow builders hard at work.
