A native of Chillicothe, Ohio, he came to us from Chillicothe High School, where he was on the football, basketball, and track teams and captained the football and track teams in his senior year. He was elected to the National Honor Society and to Quill and Scroll, an international high school journalism honor society.
At Princeton, Dan majored in philosophy within a pre-med program. He was a member of Tiger Inn, the Pre-Medical Society, the Committee on Athletics of the Undergraduate Council, and the varsity football and track teams. His roommates were Forrest Walpole and Byron Rose.
Dan earned a medical degree from Yale Medical School in 1967, then completed his training at the Cleveland Clinic and joined its cardiology department. He was viewed as a visionary in the field of interventional cardiology and was among those who revolutionized the treatment of heart disease. In December 1980, Dan and his peers became the first to perform an angioplasty at the clinic. He was appointed director of the clinic in 1982, and during his time there he treated thousands of patients including celebrities and royalty from all corners of the globe.
In 1983, Dan relocated to Pensacola, Fla., where he joined the Northwest Florida Heart Group. In retirement, he focused on the things he loved most: his family and gardening. His favorite place outside of Pensacola was Big Sky, Mont., where he and his family went annually to ski. He chose Big Sky as his final resting place, where his ashes will be spread.
Dan is survived by Camille, his wife and the mother of his sons, William and Bradley, and his former wife Margery Moses Phillips, mother of his son, Daniel Jr., and daughter, Elizabeth Phillips Kohl; and nine grandchildren.
