Inspired by his mom, the Grey’s Anatomy star and sisters Mary and Alicia partnered with Central Maine Medical Center – where Amanda had been treated – to found The Patrick Dempsey Center for Cancer Hope & Healing in their native Lewiston.

“For a family to get a cancer diagnosis is devastating, and all the information out there can be overwhelming,” Dempsey, 48, told reporters at the center’s opening that spring. “I talked to my sister[s] about a place where people could go for all this type of information and help. Knowledge is power.”

Celebrating its sixth anniversary this year, the Dempsey Center “provides free cancer support, education and integrative medicine services to anyone impacted by cancer, regardless of where treatment is received,” a statement posted on the official website reads. Since its inception, over $5 million has been raised to support the Center and its goals.
