Our clinic has incorporated the specialty of dermatology and allergy into one clinic, as we believe many allergic conditions present as dermatological symptoms. 

Our providers perform general dermatological exams, management of any dermatological condition and multiple procedures which include skin biopsies, skin cancer excisions and PRP wound care. We do offer pediatric dermatology care. 

We are able to provide complete allergy scratch testing for common Arizona airborne allergens. We do NOT provide food testing and our allergy clinic does NOT treat pediatric patients. Our allergy lab provides a flexible schedule at both office locations so patients on immunotherapy have options convenient to their schedule.
