Dr. Zorian P. Trusewych
Dr. Zorian Petro Trusewych, 72, of Quincy, Illinois, passed away peacefully at his home, surrounded by loved ones, on February 22, 2026.
Born on June 21, 1953, in Chicago, Illinois, Zorian grew up in inner-city Chicago, the son of Ukrainian patriots who relocated after surviving the Holocaust.
At age 19, Zorian enlisted in the United States Army, serving in Vietnam as an airborne ranger with the 101st Airborne Division. He later pursued higher education and medical school, returning to military service through the Army scholarship program. He completed his internal medicine residency at Walter Reed Army Medical Center in Washington, D.C., followed by a fellowship in Allergy and Immunology.
During his 12 years of military service, Zorian rose to the rank of Lieutenant Colonel. He served at the Pentagon during President Ronald Reagan’s administration as Assistant Chief for Professional Services and was the medical officer for Reagan’s inaugurals. From 1986 to 1988, he served as Chief of Allergy and Immunology at Irwin Army Community Hospital in Fort Riley, Kansas. His military career reflected his discipline, leadership, and dedication to service.
After separating from the Army, Zorian returned to Chicago to be near his parents and continued his medical career in academic and suburban practice settings. He later moved to Quincy, Illinois, where he practiced allergy and immunology at Quincy Medical Group. Following his time at QMG, he continued serving the community at Blessing Hospital and later as Medical Director at the Illinois Veterans Home. He also served as Medical Director for Wexford Health Sources at the Western Illinois Correctional Center, continuing his dedication to patient care and medical leadership.
Zorian was a highly intelligent and respected physician who took pride in his knowledge and convictions. He was known for being opinionated and never shy about sharing his thoughts — a trait that made for lively conversations and strong leadership. Outside of medicine, he enjoyed fixing anything that needed repair, camping, and fishing whenever he had the opportunity. He valued self-reliance, the outdoors, and staying busy with his hands.
Zorian is survived by his life partner, Stacy Trautvetter of Quincy, IL; his daughter, Tamara Hartley (Benjamin) of Wisconsin; his son, Stefan Trusewych (Chauntel) of California; their mother, Sandra Trusewych of Wisconsin; his brother, Timothy Trusewych (Maria) of Chicago, IL; his nieces and nephews, Ruslan, Adriana, and Marco; and his grandchildren, Zevin, Orion, and Archer. He is also survived by Stacy’s children, Cody Johnson (Emily) of Augusta, IL, Catelynn Weatherford (Billy) of Loraine, IL, and Casey Johnson (Emily) of Liberty, IL; and their children, Lyndi, Tristan, Raelynn, Zoey, Will, Carter, Beau, Mallory, and Ryley.
He was preceded in death by his parents, Bohdan and Halyna Trusewych.
He leaves behind a legacy of service, strength, intellect, and dedication that will be remembered by all who knew him.

Doc was Medical Director at the Veterans Home during my entire tenure as Home Administrator. He was a one of a kind and hands down the best MD I ever worked with in my LTC career. His medical knowledge was unbelievable, and I was always impressed by his ability to explain medical issues so people could easily understand. He was not just a colleague but we also became friends. I enjoyed our conversations and learned so much from him. He will be missed.
I accompanied Dr. T on weekly “wound rounds “ at one of the units of the Veterans Home at Quincy. He came to see these Veteran men at a time when “who” they were was more important to them than what today’s medical issue was. He talked to these soldiers as he examined them, in their own language, and shared stories with them, reminding them of who they were. During each visit it he shared with them what it meant to have served their country. Not only was he their doctor, but their comrade as well, and if it made him late to the next meeting so be it. Thank you for teaching me many things, Dr. Trusewych. Rest well, Honorable Soldier.
Thank you for your wonderful comments. It is the part of Zorian I loved the most.
Thinking of you, Sandy.
Doc Trusewych was a very intelligent, feisty, good humored doctor. I can remember as an RN at IVH, I would tell him about a few signs and symptoms a resident would be having, and he often would already have the correct diagnosis right at that moment. Super wonderful intelligent physician.RIP🙏🏻
We were all saddened by the news of Zorian’s passing. He was an exceptional physician whose breadth of knowledge helped so many patients. The staff of DuPage Family Medicine sends its most sincerest condolences. May he rest in peace.
