Office Manager

Minimally invasive, patient focused, personalized care.

I am sub-specialized and board certified in General Gynecology and Gynecologic Oncology, the surgical care of pelvic problems from benign to malignant (non-cancer to cancer ). I have extensive experience in all aspects of gynecologic surgery and gynecologic cancers: of the ovary, uterus, cervix, and vulva and trophoblastic disease. I am board certified in gynecology and gynecologic oncology. Please see my resume. Over the last 22 years, I have become particularly adept in performing 95% of my surgeries using laparoscopic techniques (surgery by keyhole-size incisions). With this minimally invasive surgical approach, patients have less pain, lose less blood, stay in the hospital fewer days, return to work more quickly and have tiny scars on their abdomens.


My practice in Portola Valley in Gynecological Oncology (cancer surgery and complex pelvic surgery) is based at Sequoia Hospital in Redwood City, CA. I welcome new surgical and gynecological cancer patients from around the world.

Many patients from afar will choose our "One-Stop" option well in advance of their surgery: planning ONE VISIT to the bay area for both the office visit and surgery the next day. With this option, all reports (your medical history, all x-rays, microscopic slides, cardiac clearances, and blood tests), are faxed to our office for my review. Then I call and we plan your visit together: with office consultation on the day before we operate, and then surgery the next day.

Many patients are referred for specialized consultation because of a known or suspicious lesion, a pre-cancer or a recurrent cancer. Some need major surgery for a benign reason. We will give you the most current  information available about your problem, anticipating that your understanding will make your treatment more successful.


Dr. O'Hanlan provides extensive literature for your review in the waiting area, anticipating that you will want to educate yourself about your health to prevent disease and live well. In addition, she has co-authored a book of healthy aging for women called Natural Menopause: The Complete Guide (Addison Wesley, 1996). This book, combined with the specific literature provided in the waiting area on breast cancer, uterine cancer, cervical cancer, vulvar cancer, osteoporosis, heart disease, colon cancer, endometriosis, weight management, sexuality, and hormone therapy provide you the best references of up-to-date, state-of-the-art prevention and therapy.


Becoming educated on your own will enable you and Dr. O'Hanlan to fine-tune your health in a collaborative relationship. Please arrive early or stay late after your appointment to read the many women's health articles provided.
