    Philosophy of Care

    Our practice emphasis is on primary health care of adults. As a gay doctor, I have a special focus on primary care of gay men and lesbians, including patients with HIV/AIDS. We believe that patient education is a keystone in understanding any medical condition and that providers and patients must be active partners in health care.
