Mark DeGalan Obituary
He was born June 3, 1959, in Flint, Michigan, the son of the late Edward and Virginia (Hittel) DeGalan.
Mark graduated from Flushing High School (Flushing, MI 1977) and received his BS in chemistry from the University of Michigan – Flint (1981), PhD in Pharmacology at University of Michigan (1986), MD from University of Miami Florida (1990), Residency and Fellowship in Radiology/Nuclear Medicine at University of Indiana (1990-1995).
He retired from the Cleveland Clinic (Mercy Hospital) after 30 years of service as a radiologist.
Mark was a member of UM Alumni Association and multiple professional organizations. Always a strategist, he enjoyed chess, military history, and grand strategy video games. He treasured his backyard fish and frog pond, UM football games (In heaven Michigan always wins - Go Blue!), and had much pride in spoiling his beloved family. As a paraplegic and cholangiocarcinoma survivor, his relentless courage and endurance inspired all. He lived with honor, grace, humor, and joy.
Mark is survived by his wife, Karen JH DeGalan; children, Luke H DeGalan, and Anna J (Kristin Vadnais) DeGalan; brothers, Edward (Susan) DeGalan Sr., and Steven (Karen) DeGalan; nephews, Jason (Lyn) and Joel Short, Edward III and Ethan DeGalan, Craig (Trisha), Neil Hamilton, and Steven Eric DeGalan; great nieces and nephews, Natalie, Annalia, Andrew, Stella Short, Morgan and Dylan Hamilton.

So many fond memories and sports conversations with Mark in my 24 years working with him in radiology. How lucky I was to have worked with Mark.

You know you have our love and support at this time and forever. Mark was a very special man and a wonderful friend. You could always count on Mark for a friendly smile and a good story. You knew it was going to be a good story when those eyes began to twinkle. We will miss him, but are so grateful to have been able to call him friend.
