About us

North Texas Allergy & Asthma Associates was founded by Dr. Harvey Black in 1927. Dr. Black spent many years studying the causes of allergies and over time developed a test for allergy. He was a President of the American Society of Clinical Pathology, and 1945 coauthored the textbook "Practice of Allergy" and was truly a pioneer in his time. In 1950 James Holman, M.D. joined the practice and took over after the death of Dr. Black. While building his allergy practice, Dr. Holman served as an associate professor of pharmacology at Southwestern Medical School in Dallas and served as head of the Parkland Allergy Clinic from 1951 to 1980. Dr. Holman was eminently qualified for this role, for he had studied at Southwestern under Dr. Tinsley Harrison and at the University of Virginia. Dr. Holman has written many articles and papers on allergy and immunology, and was instrumental in the development of various novel therapeutic treatment options during that time.
