Julie Scofield, executive director of the National Alliance of State and Territorial AIDS Directors (NASTAD), is leaving her position after 22 years. Scofield made her announcement in a NASTAD blog post she titled “Why I’m Stepping Down and Passing the Leadership Baton.” She cites a “convergence” of reasons for her departure.

In her post, Scofield also shares that NASTAD deputy executive director Murray Penner will become executive director of the advocacy and policy organization effective April 1. Penner, a gay man living with HIV for nearly 30 years, is both an HIV and hepatitis C treatment activist. He has worked at NASTAD since 2001.

In 1993, Scofield helped open NASTAD’s doors to advocate for an urgent response to the AIDS epidemic across the country. In 2000, the organization expanded its efforts to include viral hepatitis. NASTAD now supports health programs in 59 U.S. states and territories, as well as 14 countries, and has a yearly budget of more than $12 million.

Although Scofield has made no definite plans for her future, she and Penner are discussing how she can stay connected to NASTAD, such as working on projects like the organization’s 2015 “Black Lives Matter” campaign.
