Never mind that Serena Williams has 21 grand-slam titles. Or that she’s the greatest athlete ever. It’s the work she does in her spare time off the tennis court that should be highlighted.

Over the last couple of days, Williams has been building a school in Jamaica. Yes, you read that right.

Williams’ organization, the Serena Williams Fund, partnered with Helping Hands Jamaica to build the Salt Marsh Primary School.

And if a picture is worth a thousand words, this video of Williams getting her “Bob the Builder” on is worth a million.

The ribbon-cutting ceremony was also captured on video, and one can only imagine how many happy kids there were. Seriously, Williams can do no wrong in our book.
