Ben Platt and Sister-in-Law Courtney Platt Are Fighting MS With Music and Dance

Multiple sclerosis hit home for actor and singer Ben Platt when his sister-in-law Courtney Platt was diagnosed with the disease. The two have now teamed up with Bristol Myers Squibb for a campaign called “MS in Harmony” that makes music therapy treatments available online. It’s one of many projects for Ben Platt, who has a movie version of his Broadway hit “Dear Evan Hansen” and a new album on the way.
