On Saturday (Dec. 2), Justin volunteered at the Los Angeles Regional Food Bank and helped pack meals for kids. He was there along with his costars Jason George and James Pickens Jr., as well as Grey’s Anatomy co-showrunner William (Bill) Harper and former writer/EP Mark Wilding. Check out the photo Jason posted on Instagram below.

William Harper tweeted about the Grey’s fam volunteering with their own fams, and donating to the LA Food Bank or supporting local food banks.

So much fun and such fun work with our #GreysAnatomy Fam and our own fams! Support the @LAFoodBank today where your 1$ supplies 4 meals for hungry kids, families and seniors! Or support your local food bank! Thanks @JasonWGeorge @7JustinChambers and @therealjpickjr https://t.co/RBSsVsNsDa
