Peter Mazzoni

Mazzoni Center is a 501(c)(3) nonprofit health care provider in Philadelphia, Pennsylvania, that serves the LGBT community.

To provide quality comprehensive health and wellness services in an LGBT-focused environment, while preserving the dignity and improving the quality of life of the individuals we serve.

Founded in 1979, the Mazzoni Center was originally known as the Lavender Health Project, a volunteer health subcommittee at the Gay Community Center (now known as the William Way LGBT Community Center).

The group was formed just two years before the HIV/AIDS epidemic was first recognized.

Its areas of original focus included clinical services for gay men & lesbians, health education, and advocacy work; however, responding to the AIDS epidemic became the health agency's primary concern during the 80's and early 90's.

In 1981, when the group became incorporated, it changed its name to the Philadelphia Community Health Alternatives (PCHA).

The PCHA quickly organized the Philadelphia AIDS Task Force (PATF), which became the first AIDS service organization in Pennsylvania.

Dr. Mazzoni had served as the clinc's medical director, was an openly gay and HIV-positive physician, and died in 1990 at age 31.

Today, the Mazzoni Center is the oldest HIV service provider in the state.

In 2003, the organization renamed itself to the Mazzoni Center, after Dr. Peter Mazzoni, a volunteer physician and board member.

In August 2017, the Mazzoni Center cancelled a Trans Health Conference panel discussion on detransitioning.

The conference organizers said, "When a topic becomes controversial, such as this one has turned on social media, there is a duty to make sure that the debate does not get out of control at the conference itself. After several days of considerations and reviewing feedback, the planning committee voted that the workshops, while valid, cannot be presented at the conference as planned".
