Mark Biagtan, MD, is a UW Health allergy and immunology doctor. He diagnoses and treats people with a wide range of allergic conditions. He sees patients for seasonal and environmental allergies, asthma, food allergies, drug allergies, recurring sinus infections, swelling and hives (a bumpy, itchy skin rash).

Dr. Biagtan works with patients to identify what’s causing their allergic reactions. He recommends the latest treatments to manage their conditions and offers tips to reduce bothersome daily symptoms. For the patient’s convenience, Dr. Biagtan and his team provide a written summary of each visit, along with instructions.

To ease any stress his patients might feel, Dr. Biagtan listens closely and answers all their questions. He provides education about their condition and assures them that if initial treatments don’t work, he’ll partner with them to find other options.

Dr. Biagtan’s goal is to help his patients feel better, breathe more easily and enjoy a safe, healthy life.

In addition to patient care, Dr. Biagtan serves as a clinical assistant professor in the Department of Medicine, Division of Allergy, Pulmonary and Critical Care at the University of Wisconsin School of Medicine and Public Health.

I give my patients the same high-quality care and attention that I want for myself and my family members.
