Allergy, Asthma + Immunology

Whether the goal is fast relief for occasional allergy symptoms or a comprehensive, long-term treatment plan, our allergy, asthma, and immunology specialist, Dr. Michael Sullivan, can provide personalized care for your particular needs.

Dr. Sullivan’s sole practice is to study, diagnose, and treat immune system conditions, including allergic disease and related symptoms and reactions - issues that affect many millions of Americans. Dr. Sullivan puts each patient at the center of care and combines traditional medicine with other evidence-based therapies that have proven to be effective in reducing allergy symptoms.

Dr. Sullivan, a native of Omaha, graduated from Creighton University Medical School and pursued a 3-year Internal Medicine residency and a 2-year fellowship in Allergy, Asthma, and Immunology with the United States Army at Walter Reed Army Medical Center, in Washington DC. Dr. Sullivan said, “The US Army really widened my vision of the world and I will forever be grateful for my time in the military. It transformed me into the allergist I am today. Now I have the joy of treating patients both young and old who exhibit symptoms of allergic rhinitis, recurrent infections, asthma, hives, eczema, food allergies, drug allergies, bee sting allergies, and many more allergic and immune problems.”

Dr. Sullivan holds specialty clinic hours at Henderson Health Care on a quarterly basis. If you struggle with allergies and/or asthma, consider talking with your primary care provider about scheduling an appointment with allergy, asthma, and immunology specialist, Dr. Michael Sullivan.
