About Me

Physicians serve as “natural attorneys” for patients, helping them to exercise their right to medical care. As a physician, I believe I have “assumed responsibility for a sublime mission” to help patients get the care they need, with as much of it provided at the local level as possible. 

I began studying medicine to help bring about a more equitable distribution of resources, to provide care to those who might not otherwise be able to access it, and to ease the financial burdens associated with health care. I chose to specialize in family medicine because that is the skill set most needed in remote, rural and international settings.

I completed fellowship-level training in high-risk obstetrics, including cesarean delivery, colonoscopy, endoscopy, ultrasound, and other advanced procedures. I have a specialization in HIV medicine, as well as travelers’ health and tropical medicine. I have a special interest in gynecological health and infertility, approached from the perspective of restorative reproductive medicine. I am trained in fertility awareness-based methods of family planning, and am a Certified FertilityCare Medical Consultant. 

Additionally, I have an interest in healthcare ethics and hold a master’s degree in philosophy and a certificate in healthcare ethics.

Spending time with patients is a highlight of this profession, and it’s rewarding to provide them with the care they need
