Jeffrey Mitchinson, M.D.

A native of Tecumseh and New Hudson, Dr. Jeffrey Mitchinson was inspired by a simple yet profound goal: to help people. Encouraged by his minister father, he attended medical school at the University of Michigan. It seems an interest in medicine runs in the family. His two siblings – also encouraged by their father – now work as a radiologist and epidemiologist/massage therapist respectively. 

At college, his fascination with anatomy combined with an interest in technology led him further to study radiology, sub-specializing in cross-sectional imaging and ultrasound. 

Dr. Mitchinson views the continual march of radiologic technology with fascination. It has moved from viewing films on lit panels to today’s powerful real-time digital imagery. However, he notes RMI’s approach to reporting has always been to fully question findings, obtain input from colleagues, and work closely with referring physicians. This is an approach which sees RMI as a collaborator with physicians, instead of merely a service provider. There is always, he said, an emphasis on problem solving. 

With the rise of artificial intelligence, Dr. Mitchinson notes the ability to solve challenging medical problems keeps improving every day — leading to ever-better patient outcomes.

Christopher C. Murray, D.O.

Dr. Murray developed an interest in medicine while working at his first career as a firefighter-paramedic for the City of Boca Raton, Florida. While employed there with his identical twin brother, he decided to go back to college and then on to medical school. During his internship, he greatly enjoyed the radiology rotations and decided to become a radiologist. His subspecialty is musculoskeletal imaging, having completed a one year fellowship in MRI at Harper Hospital/Detroit Medical Center.

He is most fulfilled and content while spending time on the ocean or in the woods. He is an avid ocean fisherman and diver, and proudly notes he has not missed deer hunting season in 25 years. His three children have become accomplished hunters as well.

Dr. Murray states the greatest benefit working at RMI is the family-like atmosphere and professionalism of its staff.

Brian Sabb, D.O.

Dr. Sabb entered medicine from a strong desire to help people recover from illness so they could return to happier lives. He specialized in radiology as it encompasses all aspects of medicine, allowing for solutions for many different patient problems from musculoskeletal to neurological.

A doctor of simpler pleasures, Dr. Saab enjoys spending his free time with his children, exercising, and watching action and comedy movies.

Sabb notes the teamwork and collegiality of RMI is a great motivator. He said the staff works together to efficiently help patients and communicates well with their referring physicians, which is critical for good patient care.

Dennis Vollman, D.O., FAOCR

Dr. Dennis Vollman’s passion for how things work led him to a lifelong career in radiology. Upon completing dual bachelor’s degrees in chemistry and applied mathematics/computer science, a friend convinced him to take a class in anatomy and physiology, leading to an interest in medicine.

While attending Michigan State University (and considering a career as an internist), his future wife introduced him to radiology. That specialty was the perfect combination of biology and engineering – a way peer into how the body works.

Dr. Vollman’s career in radiology was fruitful. His work tenure includes time at Garden City Hospital, Oakwood Hospitals, Riverside Radiology Specialists, and Southgate Radiology. He acquired and ran Southgate Radiology in 2008, before selling it to RMI in 2018.

Multiple appointments and honors have hallmarked his career, including induction as a fellow in American Osteopathic College of Radiology (AOCR) in 2004, working as department head or chief resident at many of hospitals he worked at, and serving 10 years on the American Osteopathic Board of Radiology (AOBR) – two of those years as its chairman.

He is especially proud of serving 25 years as a radiology residency director. He sees that work with the 50 doctors he mentored as his legacy.

In his off hours, Dr. Vollman pursues a love of golf, working hard to get in 100-plus rounds each year.

He sees RMI’s approach to outpatient radiology reflecting the values he promoted at Southgate Radiology — an emphasis on personal service to patients and working as the “doctor’s doctor” for referring physicians. The future looks bright, he adds, with ever-evolving technology such as artificial intelligence to assist – but not replace – the work of radiologists.
