Women's Care
We are committed to providing high-quality, comprehensive primary and specialty health care to women. Dr. Harter and Dr. Ahmad understand the unique health care needs that women face not only in their day-to-day wellness, but in their long-term health care as well.
Internal Medicine
Internists are physicians who specialize in the prevention, detection, and treatment of illnesses in adults. Our physicians have 30 years of combined experience in internal medicine treating such illnesses as diabetes, heart and lung disease, chronic headaches, and more.
Headache Treatment
Dr. Harter has long had an interest in headache treatment, since she herself and a number of friends and relatives suffer from migraines. She became one of only two physicians in Arizona to pass the first national board exam in headache medicine, in 2006.
Allergy Care
Dr. Ahmad and Dr. Harter offer allergy care with treatment involving a form of immunotherapy known as Sublingual Immunotherapy. This treatment is administered by placing a sublingual drop under the tongue, which can be done in the comfort of your home and is monitored every 12 weeks by your physician.
