WHO: Rico Rodriguez plays Ed O’Neill’s deadpan stepson, Manny, on the Emmy-winning ABC sitcom “Modern Family.”

WHAT: Camp Ronald McDonald for Good Times won Rodriguez over with its cause: Founded in 1982 by a group of individuals who dreamed of a place where children who have had their lives devastated by childhood cancer could recapture what being a child is supposed to be, the camp programs provide year-round support for families and children impacted by cancer. Camp is offered to any child from infancy to age 18 who has had cancer or a similar condition or who has a sibling with one of these diseases, at any stage of illness or treatment — at no cost to their families.

WHY: “It breaks my heart to see kids who are sick with cancer, AIDS and other illnesses like that,” Rodriguez says. “What stood out about Camp Ronald McDonald for Good Times was that they help kids. They help them have fun and go to camp where they have arts and crafts, drama club and they get to play sports. The camp runs all year round, and about 1,900 kids went to camp last year.”

WHAT’S NEXT: Rodriguez will attend Camp Ronald McDonald’s 19th annual Halloween Carnival on Sunday on the Universal Studios backlot.
