Thomas Richard "Tim" Mainzer, M.D., 88, of Westminster Woods at Huntingdon, and formerly of Jay, N.Y., passed away at 5:56 P.M. on Wednesday, March 25, 2020, at Westminster Woods, Huntingdon. Born Nov. 27, 1931, in Clearfield, Pa., he was a son of the late Francis S. "Frank" Mainzer, M.D. and Dorothy (Kirkwood) Mainzer. He was united in marriage to the former Barbara June Bauer on July 2, 1955, in Ardmore, Pa. Mrs. Mainzer preceded him in death on Jan. 15, 2004.

He is survived by four children, Thomas R. Mainzer Jr. of N. Syracuse, N.Y., Susan M. Mitchell of Richmond, Va., Nancy B. Mainzer of Somerset, N.J., and Gary W. Mainzer of Harrisburg; six grandchildren, Thomas R. Mainzer III and his wife, Emily, of State College, Michael T. Mainzer and his wife, Lara Metcalf, of Atlanta, Ga., Erin H. Mainzer of Syracuse, N.Y., Brenna K. Mitchell, Shelley A. Mitchell, and Christina M. Mitchell, all of Richmond, Va.; and a great-granddaughter, Kathryn A. Mainzer. He is also survived by a brother, John E. Mainzer and his wife, Sylvia, of Huntingdon; two sisters-in-law, Jane D. Mainzer of Powell, Ohio, and Joan H. Mainzer of Erie; and many nieces and nephews.

He was preceded in death by two brothers, Francis K. Mainzer, M.D and Peter J. Mainzer; a sister, Cynthia Mainzer; and two sisters-in-law, Brigitte I. Mainzer and Ellen A. Mainzer.

Having moved from Curwensville, Pa., to Huntingdon, Pa., in his early childhood, he attended Huntingdon public schools until 10th grade. In 1948, he entered The Hill School in Pottstown, where he graduated in 1949. Following high school, he was accepted to Hamilton College in Clinton, N.Y., graduating in 1953 with a Bachelor of Arts degree. He was then accepted to Jefferson Medical College, Philadelphia, and graduated in 1957 with his medical degree.

Upon graduation from Jefferson, he and his wife moved to Akron, Ohio, where he completed his internship and residency in general surgery at Akron Children's Hospital.

Following his residency in 1963, Dr. Mainzer entered active duty in the U.S. Naval Reserves as a medical officer. He was assigned to the U.S. Naval Hospital at Bremerton, Wash., as a Lieutenant Commander. In April of 1965, he was temporarily assigned to the 3rd Medical Battalion of the 3rd Marine Division in Da Nang, South Vietnam. He spent three months in Vietnam and was honorably discharged from active duty in July of 1965.

After his military service, he and his family moved back to his hometown of Huntingdon, Pa. In late 1965, he established a private practice as a general surgeon affiliated with J.C. Blair Memorial Hospital, Huntingdon, in partnership with Dr. Charles Reiners. He served for 16 years as an elected member of the hospital's Board of Directors, and terms as President of the Medical Staff and Chief of Staff. Dr. Mainzer retired from his medical practice in 1991. Following his retirement, Dr. and Mrs. Mainzer moved to a second home that they owned in Jay, N.Y.

Dr. Mainzer was a Fellow of the American College of Surgeons; a member of the Pennsylvania Medical Society and the American Medical Association; and certified by the American Board of Surgery.

He was a former active member of St. John's Episcopal Church, Huntingdon, where he served as a lay reader and sang in the choir.

Dr. Mainzer was an avid outdoorsman who enjoyed hiking, backpacking, snowshoeing, cross-country skiing, bicycling, kayaking, and canoeing. He also enjoyed domestic and foreign travel, woodworking, gardening, model railroading, home improvement, and personal computing. He served terms as a board member and officer of the Ausable Acres Property Owners' Association in Jay and volunteered many hours constructing and maintaining foot trails in "The Acres."
