Darren Binder, vice president and deputy general counsel of Bon Secours Health System, Inc., based in Marriottsville, MD, is co-founder of City Dogs Rescue, a volunteer-run nonprofit in Washington, DC. Why? “Rescue is stressful work, but it’s enormously rewarding, and these dogs often have no one else to help them.” Stats: Rescued more than 800 dogs from high-kill, overcrowded shelters since 2011. Pets: Grew up with Gidget, a black lab; now has a rescue dog, Cody, and two rescue cats. Website: citydogsrescuedc.org.
