about us

Dr. E. Malcolm Field came to Saginaw, MI in 1961. It was an easy choice for him because it was an area that was neurosurgically undeserved. Dr. Field knew that he could make a change and help treat patients afflicted with neurosurgical illnesses who previously had to travel to Detroit or Ann Arbor to seek care. What Dr. Field didn't anticipate was the need to the areas north of Saginaw as well. He was contacted by administrators and physicians from various areas of Northern Michigan asking him to provide care for the people in their communities as well. This started the remote clinic locations which continues to this date where we travel to hoping to make it easier for patients to have the neurosurgical care they need closer to home.

​

After years in private practice, Dr. Field, in conjunction with St. Mary's Hospital, started the Field Neurosciences Institute (FNI) in 1988. The FNI was founded on three pillars: treatment of neurological diseases, education, and research. The FNI is one of the few neurological institutes to exist outside of an academic university hospital setting and makes us so unique. The institute have raised funds over the years to support various educational programs, fund top of the line research, support and provide charitable support to the Saginaw area, and purchase cutting edge surgical equipment to Ascension St. Mary's Hospital, making us a center of neurosurgical excellence.

​

In 2013, Dr. Field, Dr. Salibi, and staff joined Ascension St. Mary's Hospital. In 2014 Dr. Joseph Adel, a fellowship trained cerebrovascular, endovascular and skull based neurological surgeon joined the group. In 2018, Dr. Eric Bialaski, fellowship trained in a comprehensive and reconstructive spine surgery, was added. 2019 saw the additions of: Dr. Nnenna Mbabuike, cerebrovascular and endovascular fellowship trained neurosurgeon, and Dr. Timothy Gates, fellowship trained in minimally invasive and comprehensive spine surgery.

​

In March of 2020, Ascension St. Mary's Hospital became a Joint Commission Certified Comprehensive Stroke Center, the only in our region and north of Flint, joining only eleven other hospitals in Michigan carrying the distinction. With acute stroke, time is of the essence. Being a certified comprehensive stroke center means that we have the medical expertise and equipment needed to provide comprehensive care close to home, making travel south unnecessary saving valuable time. This provides reassurance and comfort to the patients and their families.

​

Our line up makes Ascension Medical Group Neurosurgery one of the largest groups north of Detroit with a medical staff and expertise capable of providing comprehensive care to the neurosurgical patients.
