United Allergy Services works with providers to offer allergy sufferers long-term relief through a safe, effective, home-based treatment. We’re headquartered in San Antonio, Texas. Since being founded in 2009, we’ve grown to almost 500 employees, and work with more than 2,450 practitioners across 20 states. During that time, we’ve conducted more than 575,000 allergy tests and served over 350,000 patients with over 36 million immunotherapy treatments administered — 83% of those being done in the patient’s home.

The UAS Immunotherapy model has shown:

  • 95% of patients had improved allergic rhinitis scores
  • 82% of patients reported diminished use of medications
  • 88% of patients reported improved Rhinoconjunctivitis Quality of Life Questionnaire scores after immunotherapy
  • 86% would recommend allergy testing and immunotherapy to friends and family
  • 82% feel comfortable administering immunotherapy injections
  • 85% of people treated with immunotherapy for hay fever may achieve allergy symptom relief within the first year of starting immunotherapy
  • After 3-5 years of complete immunotherapy treatment, most patients experience little or no allergy symptoms

Our providers say:

  • 90% would recommend United Allergy Services to colleagues
  • 100% believed the CAT/CAS in their practice was knowledgeable about allergy testing and immunotherapy
  • 99% believed the CAT/CAS in their practice interacted well with patients and with clinic personnel
  • 98% believed allergy testing and immunotherapy services are an integral part of patient services

Our protocols have been developed and are continuously evaluated by our Chief Medical Officer Frederick M. Schaffer, M.D., a board-certified allergist. They are also overseen and evaluated by the United Allergy Services Medical & Scientific Advisory Board, which is comprised of three board-certified allergists and three academic doctors from the largest antigen suppliers in the country, Stallergenes Greer and Jubilant HollisterStier, who serve as scientific advisors.

Revolutionize allergy care in America. We are improving access to millions of allergy sufferers that would not receive advanced allergy care without United Allergy Services.
