We post reviews for MSK healthcare providers who have at least 30 patient experience surveys completed. If you do not see reviews for a provider, it may be because they do not yet have enough survey responses, or the provider may not be part of the group of healthcare providers included in the survey.
Only outpatient providers are included in the survey. Healthcare providers who only work in the hospital or in urgent care are not included in the survey. Pathologists or researchers who do not provide direct care to patients do not have reviews.

I am a medical oncologist with a primary focus on the medical treatment of patients with gynecologic cancers. I work very closely with a team of surgeons, oncologists, and radiation therapists to determine and provide the best treatment for each patient with these diseases.
My research initiatives include improving the treatment options for women with recurrent ovarian cancer and uterine sarcomas.
