Dr. John Mavromatis, PhD, passed away peacefully at home on March 21, 2025, in East Bloomfield, NY, at the age of 80. 

John was a fiercely loving and devoted husband to Susan Parmele, with whom he shared 41 years of marriage. He is also survived by their two sons, Andrew (Erin) and Timothy (Katie). He was predeceased by his parents, Anne Coulakis and Spiros Mavromatis

Born May 16, 1944, in Brooklyn, NY, John graduated from Fort Hamilton High School. He earned his BA from Hobart College in Geneva, NY, before obtaining his PhD in Cognitive Psychology from the University of Pittsburgh in 1970. His distinguished academic career spanned 47 years at St. John Fisher College (now University) in Rochester, NY. There he served as Chair of the Department of Psychology for many years. He contributed to several statistics for social sciences textbooks, pursued research in areas of learning and history and systems in psychology and was actively involved in numerous academic committees.  

 Beyond academia, John dedicated time to his community. He served on the Bloomfield Central School Board, volunteered with Boy Scout Troop 54/55, and coached first-year youth lacrosse in the Bloomfield/Honeoye League. A lifelong Episcopalian, he was an active member of St. Peter’s Episcopal Church in Bloomfield, NY, where he served as Warden and Chalice Bearer.  

John had a deep appreciation for life’s pleasures—gardening, bonsai and Japanese maple cultivation, mastering the art of BBQ and cooking, and savoring fine food and wine. He was an avid mystery and history reader, theater lover, movie buff, and passionate sports fan who cheered for the NY Mets and Giants but also had a soft spot for the Buffalo Bills. A collector of books, ephemera, toy soldiers and pipes, John was best known for his generosity and hospitality.  

A private gathering for family and friends, to celebrate his life, will be held at a later date.

Contributions in John’s honor may be directed to the James P. Wilmot Cancer Center, URMC or to URMC Home Care-Hospice of Ontario/Yates Counties.
