Choosing a health care provider is one of the most important decisions you will make. At Associates in Women's Health Care, we make it easy for you. Our providers are caring, compassionate, skilled physicians and nurse practitioners who are committed to your health and wellness.

Our physicians are extensively trained in the specialty of Obstetrics and Gynecology (OB/GYN). This means that they have each been trained through four years of medical school, followed by another four years in an accredited training program in OB/GYN. Each year, all of our physicians attend continuing education seminars on a variety of topics pertinent to OB/GYN. This constant renewal of their education keeps them abreast of all the latest advances in the specialty.

All of our physicians are members of the American College of Obstetrics and Gynecology (ACOG).

All of our physicians are board certified and have admitting privileges at Tucson Medical Center (TMC).
