Arizona native Dr. Desmarais was drawn to Vascular Surgery for its wide breadth and long-term patients. He provides a level of service that he would expect for his own family members. His philosophy of care is patient centered and evidence based.

Dr. Desmarais looks forward to meaningful interactions with patients whether in the clinic or operating room - and in improving symptoms or preventing complications of vascular disease.

He has many family members locally, and spent a great deal of time during his childhood in Montana. He is pleased to return to Big Sky Country for its friendly and hard-working people, beautiful scenery and outdoor opportunities. When not caring for patients, Dr. Desmarais enjoys backpacking, skiing, cycling and spending time with his family.
