John R. Schneider M.D.

John "Jack" Raymond Schneider, 88, passed away Monday, Sept. 22, 2025, at home in Grosse Pointe Shores, surrounded by his loving family.

Jack was a big man with a big heart. He carried many important titles, including husband, father, father-in-law, stepfather, grandfather, brother, brother-in-law, dog dad, friend and physician. He will be remembered well and sorely missed by all who knew him.

Jack was born May 21, 1937, in Detroit, to Evelyn and John Schneider. He grew up in Detroit and attended Denby High School and Wayne State University. Following his undergraduate studies, Jack entered the Wayne State University School of Medicine and earned his M.D. in 1963. After medical school, he served in the Michigan National Guard Medical Corps and continued the pursuit of medical specialties, earning certifications in internal medicine, hematology and medical oncology. He was a Fellow in the American College of Physicians and Detroit Academy of Medicine, of which he was the 113th president, and a member of the American Society of Clinical Oncology. Subsequently, Jack had a very long and distinguished career in the practice of hematology and oncology in the metro Detroit area. He was president of Hematology-Oncology Associates P.C. The practice he built thrives today as Great Lakes Cancer Management Specialists. Patients, peers and doctors he trained while an adjunct professor for the WSU School of Medicine consistently praised not only Jack's medical expertise, but also his humanity and compassion.

Jack is survived by his beloved wife of 11 years, Lynn; children, Kristen Van Pelt (Tom), Kurt Schneider (Betsy) and Erich Schneider (Meghan); stepchildren, Steven Carpenter and Carrie Devlin; and grandchildren, Kate and Tommy Van Pelt, Jack and Sophia Schneider, Annie, Lily and Dexter Schneider, Charlie Carpenter and Rachel, Tucker and Mason Devlin. He also is survived by his sister-in-law, Linda Schneider; and nephew, Matthew Schneider (Elizabeth). He was predeceased by his cherished first wife of 49 years, Gail Schneider; and brother, Richard "Dick" Schneider.

Jack was blessed with a long life characterized by love and amusement. He was rarely alone. He appreciated the friendships and camaraderie offered via his memberships to the Country Club of Detroit and the Yondotega Club. He gave back to his community as a board member of the Grosse Pointe War Memorial and trustee at University Liggett School. He had a uniquely sharp wit, as many can attest, and loved to dress with flair, owning one of the most extensive collections of vibrant ties one might ever see. He and Gail hosted many lively parties at their house on Oxford, where he often wound up leading sing-alongs on his grand piano, with his extensive piano repertoire played by ear, as he never learned to read music. He was proud of his family and present at many important milestone events for his grandchildren. He loved spending time at his cottage in Frankfort with friends, children, pets and many guests over the years.

His marriage to Lynn added to his circle of family and friends and enriched his life immensely. Being a stepdad and step-grandpa gave him new loves in his life.

A funeral Mass will be held at 10 a.m. Friday, Nov. 21, at St. Paul on the Lake Catholic Church, 157 Lakeshore, Grosse Pointe Farms. Family and friends may begin to gather at 9:30 a.m.
