Who We Are

For more than 50 years, Allergy Asthma Clinic LTD has served Valley residents and visitors seeking help with allergy, asthma, and immunodeficiency.

The clinic diagnoses and treats a wide variety of diseases and conditions, including hay fever, allergic rhinitis, sinus disease and infections, nasal polyps, asthma, food allergies, dermatitis, eczema, hives, antibody deficiency, and immunological disorders.

“During the past five decades, asthma and allergy rates have been surging both around the globe and especially in Arizona,” said AAC president Bart Leyko, MD. “We’ve made it our commitment to understanding what triggers each patient’s allergic or asthmatic episode rather than simply treating symptoms. It’s helped us create a unique and personalized plan for each patient.”

The practice began with one location and grew to four offices to make visits more convenient to patients living and working throughout the Valley. Serving both adults and children, Allergy Asthma Clinic has three full-time providers: Bart Leyko, MD, Chris Couch, MD, and Sherri Crespin, FNP. Each serves on a variety of educational and professional boards and has won a multitude of awards.
