The mission of the Massachusetts Department of Public Health (DPH) is to prevent illness, injury, and premature death, to assure access to high quality public health and health care services, and to promote wellness and health equity for all people in the Commonwealth. We envision a Commonwealth in which all people enjoy optimal health. Massachusetts ranks among the healthiest of states according to comparative analyses, but we face numerous challenges, including chronic and infectious disease, substance abuse, violence, preventable hospitalizations, and health disparities. DPH coordinates programs and policies to address specific diseases and conditions and offer services to address the needs of vulnerable populations. We also develop, implement, promote, and enforce regulations and policies to assure that the conditions under which people live are most conducive to health and enable people to make healthy choices for themselves and their families. We license health professionals, healthcare facilities and a variety of businesses that impact public health. We operate the state laboratory and four public health hospitals. We monitor health status and manage vital records incl...uding births, marriages, and deaths. We educate people about public health issues and work closely with local boards of health and community partners to identify and solve public health problems.
