Barry Joseph Rosen, D.O.

Barry Joseph Rosen, D.O., 84, passed away peacefully on April 4, 2026, at McLaren Hospital in Flint, Michigan, surrounded by the family he loved.

Born on March 20, 1942, in Philadelphia, Pennsylvania, Barry was the son of the late Isadore Rosen and Doris Kaiser. His life was defined by intellectual curiosity, dedicated service, and a deep devotion to his family.

Barry earned his undergraduate degree from La Salle University in Philadelphia before going on to graduate from the Philadelphia College of Osteopathic Medicine. He served as a family practitioner in Bethlehem, Pennsylvania for 15 years before completing a residency program in 1984 and transitioning to a successful career in radiology. Over the decades, he touched countless lives through his commitment to medicine and his patients. Outside of his practice, Barry was a passionate history buff. He could often be found deep in a book or absorbed in a documentary. He was also a fan of many science fiction shows. Those who knew him well knew that a conversation with Barry was never dull.

He is survived by his beloved wife of 27 years, Deanna Gasser-Rosen; his three daughters, Dina Rosen, Sharon Rabinovitz, and Susan Rudnicki and her husband Eliot, of Atlanta, Georgia; his two step-daughters, Sheryl Gasser and her husband David Niergarth of Flushing, Michigan, and Marni Gasser and her husband Tim Hermanson of Stoughton, Wisconsin; his five grandchildren, Brandon and Shayna Rabinovitz and Ethan, Miranda, and Kelvin Rudnicki; and four step-grandchildren, Harper Niergarth, Eleanora and Samuel Hermanson, and Alejandra Boone-Hermanson. He will be deeply missed by his family and the many friends whose lives he enriched.

A memorial service will be held at 1:00 p.m. on Monday, April 6, 2026, at Sharp Funeral Homes, Miller Road Chapel, 8138 Miller Road, Swartz Creek, MI 48473.

In lieu of flowers, the family kindly asks that donations be made in Barry’s memory to Congregation Chabad House-Lubavitch of Eastern Michigan or the Alzheimer’s Association.
