At the Transgender Clinic at Boston Health Care for the Homeless in Massachusetts, coauthor Brian P. Zunner (right) performs a routine examination on a female-to-male transgender patient named Markie. The clinic opened in November 2008 and provides primary care and behavioral health care, among other services, to homeless transgender patients who have difficulties accessing care because of “real and perceived negative experiences within the mainstream health care system.” For more information, go to www. bhchp. org/specialized-transgender. htm.
