Stuart H. Agren, MD–Owner/Founder of AllergyEasydr. a cropped copy

Dr. Agren has been in private medical practice since 1975.  He graduated from Tulane University School of Medicine and has served as an adjunct faculty member at Arizona State University.  He began offering allergy drops at his sublingual immunotherapy clinic in 1985 to help his patients who were not responding to traditional allergy treatment programs.  He was one of the first physicians in the country to offer SLIT for envrionmental and food allergy treatment.  He has since successfully treated more than 15,000 patients in his private practice using sublingual immunotherapy.  Dr. Agren was chosen by fellow physicians as a Phoenix Magazine “Top Doctor.”

Dr. Agren started the sublingual immunotherapy company AllergyEasy in 1995 to offer a turnkey allergy treatment program to doctors around the country.  In addition to helping physicians prescribe sublingual allergy drops, the AllergyEasy company provides allergy test kits for physicians (including food allergy test kits), testing supplies, and wholesale allergen extracts.
