Dennis Brian Costello passed away on April 2, 2022 after a long and well-fought battle with Parkinson’s Disease. He was 76.
Dennis was born on September 25, 1945 in Franklin, Massachusetts, the son of Richard “Chug” Costello and Eileen Molloy Costello and the youngest brother of the late Terrence “Terry” Costello and of Paul Costello (Emilia). He was a proud graduate of the United States Naval Academy Class of 1967 in Annapolis, Maryland and of Harvard Business School. Following graduation from Harvard, Dennis moved to Chicago, Illinois, where he met and married his beloved wife of 45 years, Joan Marie Remini. Together, they were proud parents of Caitlin Baker (Mark) and Brian Costello, as well as loving grandparents to Kerrigan and Quinn Baker. Dennis’s happiest times were with his family, on the golf course, or at a Red Sox game.
It was also in Chicago where Dennis began his 40-year career in pharmaceuticals and medical venture capital, which culminated in Dennis co-founding Triathlon Medical Ventures in Cincinnati, Ohio. His commitment to fostering revolutionary advances in the life sciences is a legacy that Dennis’s family hopes will live on in his name. As such, in lieu of flowers, the family requests that donations be made to the scientific research being done by Dennis’s doctors at Johns Hopkins Medicine, Dr. Greg Pontone and Dr. Kelly Mills, to improve the treatment and care of dementia in people with Parkinson’s Disease. Donations can be made payable to "Johns Hopkins University" and mailed to "Fund for Johns Hopkins Medicine, 550 N. Broadway, Suite 912, Baltimore, MD 21205." Donations can also be made online at https://www.hopkinsmedicine.org/psychiatry/about/charitable_giving by choosing “Parkinson’s Disease Research'' on the online giving form.
Visitation will be held on Friday, April 8 from 4:30 p.m. – 6:30 p.m. at Ginley Funeral Home of Franklin, 131 Main Street, Franklin. A funeral Mass will be celebrated in Dennis’s honor at St. Mary’s Parish, 1 Church Square, Franklin on Saturday, April 9 at 10 a.m.
