Dr. Sonstegard’s path to practicing oral and maxillofacial surgery has taken him from rural Minnesota to Norway, from the United States Army to group practice, to ultimately settling here in Washington. His work ethic, integrity, and dedication to excellence has served him well in all of his ventures and he is excited to bring his experience and expertise to the team at Mercer Island Oral & Maxillofacial Surgery.


Dr. Sonstegard’s Story

Dr. Sonstegard completed his undergraduate degree at Saint Olaf College in Minnesota. He commissioned into the United States Army through the health professions scholarship program, and earned his doctor of dental surgery degree at the University of Minnesota School of Dentistry. He then completed his oral and maxillofacial surgery residency at Joint Base Lewis-McChord in Tacoma, WA. It was there that he and his family fell in love with the beauty of the Pacific Northwest.

After residency, Dr. Sonstegard was stationed at Fort Sill, OK where he was the sole oral surgery provider and officer in charge for Fort Sill Dental Health Activity. He not only established partnerships between the local hospitals and the military community, he also served as the oral and maxillofacial surgery mentor in the Fort Sill Advanced Education in General Dentistry residency, educating and guiding recent graduates in more advanced procedures.

In his free time, Dr. Sonstegard enjoys skiing, kayaking, experimenting with different methods of brewing coffee, and building – his most recent project being a treehouse.
