Rafael “Ray” Firszt, MD


Dr. Rafael (Ray) Firszt leads Tanner Clinic’s Allergy, Asthma and Immunology specialty alongside Dr. Douglas Jones as one of the top allergy specialists in the nation. Dr. Firszt helps his patients understand and treat their specific allergies. Dr. Firszt’s practice is located at the Rocky Mountain Allergy office in Tanner Clinic’s Murray location.

Dr. Firszt completed his schooling and pediatric residency at McGill University in Montreal, Canada. He then fulfilled his residency at Montreal Children’s Hospital and his Allergy and Immunology fellowship at Duke University in North Carolina. After concluding his fellowship in 2011, Dr. Firszt moved across the country to Utah where he began his career at the University of Utah.

During his time at the University of Utah, Dr. Firszt served as Division Chief of the Allergy and Immunology Division at Primary Children’s Hospital. He developed and was the Medical Director of the Food Allergy Center at Primary Children’s Hospital in collaboration with Food Allergy and Research Education (FARE). He was involved in extensive research of food allergies and Eosinophilic Esophagitis (EoE) and has numerous publications in these areas.

Dr. Firszt has experience treating patients with a diverse set of allergic and immunological conditions. While food allergies are his primary area of focus, Dr. Firszt has extensive experience treating patients with EoE, asthma, allergic rhinitis (hay fever), sinusitis, hives, immune system complications and recurring infections.

With so many patients seeking treatment for their allergies, Dr. Firszt keenly opened his practice at Tanner Clinic where he could dedicate more time and flexibility to his patients. The board certified specialist says being at Tanner Clinic is “an opportunity for growth” for both Tanner Clinic’s allergy specialty, and for the clinic’s presence in the Salt Lake area. Yet overall, the allergy specialist’s number one priority is to continue providing top-quality care for his patients.

When Dr. Firszt is not caring for his patients, he can be found with his wife and three kids or at the ice rink playing hockey.
