Primary Care

Excellence + Compassion = Our model for complete health care. Our primary concern is you, the patient. We take pride in providing personal and friendly primary care in a caring environment.

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.

Bioidentical Hormone Therapy Specialist

Bioidentical Hormone Therapy is a valuable treatment to assist the body in healthy aging. Hormone treatment (using BioTE brand bioidentical hormone pellets) is more than just achieving optimal hormone balance and anti-aging. Hormone optimization for thyroid, DHEA, estrogen, progesterone, and testosterone in men and women can reduce the risk of age-related chronic diseases, including heart disease, diabetes, osteoporosis, and dementia. Additional benefits to hormone therapy treatments are less weight gain, brain fog, and fatigue.

Women’s Care

We are committed to providing high-quality, comprehensive primary and specialty health care to women. Dr. Harter understands 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.

Allergy Care

Dr. Harter offers 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.

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.
