Ian R Neilson, MD

Surgery, Surgical Critical Care | Surgery, Pediatric Surgery

Since I was a teenager I knew I wanted to be a surgeon. During general surgery residency at McGill in Montreal, I found satisfaction in looking after children, especially those who were acutely injured. I have done a pediatric trauma fellowship at the Children’s Hospital of Pittsburgh and a pediatric general surgery fellowship at the Montreal Children’s Hospital.

I have been an attending surgeon since 1990.  I have worked in academic surgery on the East Coast and I have been in clinical practice in the Pacific Northwest. I have been at Maine Medical Center since 2009 and I am currently the Division Director of Pediatric Surgery and the Director of Pediatric Trauma.

My wife and I enjoy living near the coast and are active in bicycling in Maine (and in Europe). We sea kayak and have done extreme trips at the foot of glaciers as well as in Casco Bay.
