Dr. Patricia Gomez Dinger

Board Certified Allergy & Immunology

Dr. Patricia Gomez Dinger is a native Texan, who completed her undergraduate training at The University of Texas at Austin. She attended medical school at New York College of Osteopathic Medicine in Long Island, New York.  She chose a career path towards allergy by first completing a three year Internal Medicine Residency at The University of Texas Health Science Center in San Antonio.  While a resident she received several awards for her research on the effects of beta blockers on patients with asthma and COPD.  During this time she also presented on the national level a new subclass of atypical acquired cold urticaria.  Having several family members who suffered with allergies, Dr. Gomez Dinger was drawn to further study the specialty of Allergy and Immunology.  She went on to complete a two year subspecialty fellowship in the field at Kaiser Permanente Southern California Medical Center in Los Angeles, California.  In 2008, Dr. Gomez Dinger’s research on the relationship of long acting beta agonist to asthma morbidity and mortality was selected as a featured poster for presentation at the National Meeting of the American Academy of Asthma, Allergy, & Immunology.

Upon completion of fellowship training, Dr. Gomez Dinger returned to San Antonio with her husband and their three children. She spent two years working as an Allergist before embarking on an opportunity to start her own practice.   Dr. Dinger is a member of Texas Allergy, Asthma & Immunology Society, San Antonio Allergy, Asthma & Immunology Society, Bexar County Medical Society, American College of Allergy, Asthma, & Immunology, American Academy of Allergy, Asthma, & Immunology, and the Joint Council of Allergy, Asthma, & Immunology.  Dr. Gomez Dinger enjoys keeping up to date on the latest medical advancements in her field and sharing them with the community taking part in numerous speaking engagements and volunteer opportunities.    When she is not working with her patients she enjoys spending time with her family and can sometimes be found at one of her two favorite places: the beach or in the mountains.
