History
Arcadia Allergy & Asthma opened in January 2019 as the Phoenix/Arcadia clinic of the established San Tan Allergy & Asthma practice. The clinic was created to bring the same evidence-based allergy and immunology care that Dr. Jain and Dr. Hill were providing in the East Valley into the central Phoenix/Arcadia neighborhood where both physicians live. In January 2019, the providers and staff of San Tan Allergy & Asthma announced the opening of the new clinic at 4840 E Indian School Road as a 'one stop destination' for immunological and respiratory care. Since then, both physicians have continued to grow their research, clinical trial, and treatment portfolios, including expanded services for eczema (the Eczema Center), oral immunotherapy for food allergies, and biologic therapies for severe asthma.
