The two-story structure replaces two facilities: the old headquarters and the old John C. Murphy Health Clinic, which was located on the site. The first floor houses the vital records office, as well as the health clinic. The clinic includes dental, women’s health, pediatrics, WIC, nutrition, X-ray, and clinical labs. The modern, spacious facility also houses health education with three community classrooms and a larger community room.

The second floor houses the Environmental Health Laboratories, which has five major sections that measure levels of environmental toxins known to cause harm to human health.
