Our practice was established in 1982 by Reuben G. Wagelie, MD,  who has over 40 years’ experience in the treatment of allergic disease. His daughter, Amy Wagelie-Steffen, MD, joined the practice in 2007. In 2011 the father-daughter team was joined by Belle Tiu, FNP. 

The practice’s main office is in Tucson, but we also serve many other Southeast Arizona communities including Nogales, Sierra Vista, Douglas, Wilcox and Safford.

We treat a wide range of allergic and immunologic disorders in both pediatric and adult patients.
