Philosophy of Care

I chose to be a ob/gyn to care for women through their lifespan and feel privileged to care for them through different parts of life. My philosphy of care focuses on listening to my patients' concerns, presenting the most up to date options, and working together to make a plan that best fits each persons' goals. No patient is exactly alike and everyone needs an invidual approach.
