Rolla Mourns Dr. Donald McMullin: Beloved Internal Medicine Physician Dies at 76, Leaves Lasting Legacy of Care

 The Rolla community is mourning the loss of Dr. Donald James McMullin, a beloved internal medicine physician whose life was defined by compassion, dedication, and an unwavering commitment to the well-being of others. Dr. McMullin passed away on Friday, February 6, 2026, just two days after celebrating his 76th birthday, leaving a profound void in the hearts of his patients, colleagues, family, and friends who had long admired his quiet strength and steady presence.

Born on February 4, 1950, Dr. McMullin, affectionately known as “Dr. Mac,” grew up with a keen sense of curiosity and a desire to serve others. The son of the late George Francis McMullin and Ruth Eileen (Moore) McMullin, he carried forward the values instilled by his family into his medical career, approaching every patient with empathy and patience. After earning his medical degree from the University of Osteopathic Medicine and Health Sciences in 1976, he dedicated decades to internal medicine, becoming a cornerstone of healthcare in Rolla. Colleagues often noted that Dr. McMullin was not defined by titles but by the depth of his listening, the attention he gave to every patient, and his relentless pursuit of medical knowledge.

Throughout his career, Dr. McMullin earned the respect and admiration of countless patients and co-workers alike. Many recall his meticulous approach to medicine, his willingness to answer questions long after hours, and his genuine interest in the lives of those he cared for. His commitment extended beyond clinical practice; he often mentored younger physicians, instilling in them the same values of curiosity, integrity, and humanity that had guided his own career.

Outside the clinic, Dr. McMullin embraced life with equal passion. He enjoyed attending live music events, spending time outdoors, and cheering on local Rolla soccer teams, but his greatest joy came from family. He shared a loving partnership with his wife, Patricia “Pat” Humberger McMullin, and together they raised three children: Steven McMullin of Columbia, Missouri; Katy Wilkins of Sandy, Utah; and Laura Turner of Willard, Missouri. He also delighted in his role as grandfather to Hudson Turner, Beckett Turner, Lexie Wilkins, and Kennedy Turner, nurturing the next generation with the same warmth he showed his patients. His family and friends remember him fondly alongside Trooper, his loyal canine companion, whose presence brought him daily joy.

Dr. McMullin’s passing leaves a legacy of service, knowledge, and unwavering kindness. The Rolla community will long remember him not only for his contributions to healthcare but for the way he connected with those around him, offering guidance, comfort, and hope. A memorial gathering will be held on Saturday, February 14, 2026, from 1 to 4 p.m. at the Rolla Senior Center, where family, friends, and community members will share stories, celebrate his life, and honor a man whose dedication touched generations.

In remembering Dr. Donald James McMullin, the message is clear: his life was a testament to the power of compassion, the importance of lifelong learning, and the profound impact one individual can have on an entire community. Rolla mourns the loss of a healer, mentor, and friend whose memory will continue to inspire all who were fortunate enough to know him.
