In 2020, Oklahoma Allergy & Asthma Clinic (OAAC) celebrates 95 years of allergy and asthma innovation. Founded in 1925 by Dr. Ray Balyeat, a pioneer in allergy treatment, OAAC has evolved over the years into one of the largest in the southwest. Patients have traveled from all over the world to be treated at the patient-centered practice. OAAC’s seven board-certified allergists are dedicated to improving the health and lifestyles of their patients.  Working alongside the physicians is a full-time Doctor of Nursing Practice and three Board-Certified Advance Practice Registered Nurse-Certified Nurse Practitioners.

The Balyeat Hay Fever and Asthma Clinic was first located at the Osler Building at 12^th and Walker. Upon Dr. Balyeat’s retirement, the clinic name changed to the Oklahoma Allergy Clinic. From 1950 to 1980, the clinic was housed at the Pasteur Building on Northwest 10^th street across from St. Anthony Hospital. In 1978, the doctors decided to relocate to the Oklahoma Health Center campus due to their strong ties to the University of Oklahoma School of Medicine and to the campus transformation of becoming a center dedicated to health and research.

In 1980, the practice moved into its new building constructed on the 325-acre Oklahoma Health Center campus as its main headquarters. In 1995, the name was updated to the Oklahoma Allergy & Asthma Clinic.  The practice has expanded in addition to the main office to four satellite locations – Midwest City, Edmond, Norman and a new location in Yukon. The main office is between Oklahoma’s trauma centers for adults and children.

OAAC allergists are on the clinical faculty at the University of Oklahoma School of Medicine where they help train and mentor medical student residents and fellows. OAAC allergists are also involved with actively sharing cutting-edge allergy and asthma information with other doctors by presenting at local, statewide and national conferences.  OAAC is an official mold and pollen counting station for Oklahoma City and provides the daily counts to the media.

OAAC’s main office is located within the emerging Oklahoma City Innovation District. OAAC has been honored as the Best Local Top Allergist by the Oklahoman’s Readers’ Choice Awards, Top Workplace in Oklahoma City by the Oklahoman newspaper, with the Torch Award from the Better Business Bureau for Business Ethics and named Top Allergists by the Journal Record business newspaper. Employees regularly serve their community by hosting fund raisers, food and school supplies drives, and volunteers for several charities across the Oklahoma City metro area.
