Wannamaker, D.O. - United Vein Centers

Keenan Wanamaker, D.O.

Board-Certified Surgeon and Vein Specialist

A Michigan native, Dr. Keenan Wanamaker is excited to return to his adopted state of Arizona – where he previously worked as a biomedical technology analyst and law firm litigation manager – to serve patients at United Vein Centers’ Phoenix office.

Board-certified in vascular surgery, Wanamaker, a U.S. Navy veteran, has earned not only a doctor of osteopathic medicine (D.O.) degree, but also both an MBA and law degree.

He brings to UVC a diverse skill set honed in the classroom, at the conference table and in the operating room. “I’ve spent half my life in different medical training programs, fellowships and graduate school,” Wanamaker says. “I think that gives me a broad skill set that’s not very common.”

Wanamaker was drawn to UVC because of a shared patient-first philosophy. An accomplished general and vascular surgeon, Wanamaker tailors his care to each individual patient’s needs.

“My goal is to make patients feel better,” he says.
