Newman Memorial Hospital is proud to announce the addition of Dr. Brian Gillis, D.O., board-certified physician and surgeon, further expanding specialty and surgical services across Northwest Oklahoma.
Born and raised in Arnett, Oklahoma, Dr. Gillis returns to the region where his journey in medicine first began. A graduate of Arnett High School, he also attended the Shattuck and Ellis County Vocational Technical Program, now known as High Plains Technology Center in Woodward, where he trained in several departments at Newman Memorial Hospital as a student. Those early experiences helped ignite his lifelong passion for medicine and patient care.
Now, after building an accomplished national career spanning more than 25 years in gastrointestinal health and surgical care, Dr. Gillis is returning home to serve the communities that helped shape him.
The addition of Dr. Gillis represents another step in Newman Memorial Hospital’s ongoing strategy to expand rural access to specialty and surgical care, ensuring patients across Northwest Oklahoma can receive advanced treatment close to home rather than traveling long distances to larger metropolitan health systems.
Dr. Gillis is board certified by the American Osteopathic Board of Proctology and the American Osteopathic Board of Family Physicians. He is widely recognized for his expertise in anorectal pathology and physiology, with a subspecialty in defecatory disorders and pelvic floor dysfunction.
He earned his medical degree from the University of New England College of Osteopathic Medicine in 1995. He completed his internship at St. Vincent Hospital Worcester and his residency at Grandview Hospital Dayton.
Throughout his career, Dr. Gillis has served in numerous leadership roles, including Chief of Surgery at Inland Hospital in Maine and Vice Chief of Staff and member of the Board of Trustees. He also currently serves on the State Medical Board in Augusta, Maine, where both Democratic and Republican leadership appointed him.
Dr. Gillis is a member of the American Osteopathic Association and the American Osteopathic College of Proctology, where he served as Past President from 2007 to 2008.
His clinical expertise includes the diagnosis and treatment of complex gastrointestinal and pelvic floor conditions. Dr. Gillis also developed and operated the largest anorectal defecatory and pelvic floor laboratory in the state of Maine, serving as a referral center for patients suffering from f***l incontinence, chronic constipation, and pelvic floor dysfunction.
Beyond clinical care, Dr. Gillis has shared his expertise nationally, lecturing at leading medical institutions including Harvard, the Mayo Clinic, the Cleveland Clinic, Massachusetts General Hospital, and the University of Cincinnati, helping develop data-driven protocols for evaluating and treating pelvic floor disorders.
Despite his national recognition, Dr. Gillis’ ties to Northwest Oklahoma remain strong. His sister, Careylyn Guthrie, lives in Woodward, and his mother also resides locally. Dr. Gillis and his wife Ingrid, an occupational therapist, share three children.
“Recruiting a physician of Dr. Gillis’ caliber who was born and raised in this region is incredibly meaningful for our hospital and our communities,” said Robyn Girton, Chief Administrative Officer of Newman Memorial Hospital. “His expertise strengthens our ability to provide advanced specialty and surgical care close to home for patients across Northwest Oklahoma.”
Dr. Gillis shared that returning to the region is a meaningful milestone in his career.
“Returning to Northwest Oklahoma and to Newman Memorial Hospital is incredibly meaningful,” Dr. Gillis said. “This is where my journey in medicine began, and I look forward to serving the communities that helped shape my life and career.”
Dr. Gillis will begin seeing patients in April in both Woodward and Shattuck.
