Three new members have been elected to AIDS United’s Board of Trustees: Cecilia Chung, June Gipson, PhD, and David Holtgrave, PhD.

Their addition brings the total number of trustees to 17 and adds to the group’s diversity and expertise, according to an AIDS United press release.

Chung, for instance, is the first transgender person to serve on the board. A health commissioner of San Francisco, she is also the senior director of strategic projects for the Transgender Law Center, the nation’s largest trans-led organization. Chung also founded Positively Trans, a project specifically devoted to transgender issues related to HIV.

Offering a different kind of experience, Gipson is the president and CEO of My Brother’s Keeper, Inc., which is run by and serves people of color and provides HIV care in and around Jackson, Mississippi. During her more than 14 years working in the public health area, Gipson founded Mississippi’s first LGBTI primary health care clinic.

Meanwhile, Holtgrave brings to the AIDS United board his global expertise in HIV prevention research, notably on how well prevention methods work and whether they’re cost-effective. He is the dean of the School of Public Health at the University of Albany, part of the State University of New York and has served on the President’s Advisory Council on HIV/AIDS and held leadership positions at the Centers for Disease Control and Prevention.

“These amazing people add decades of research expertise; a lifetime of advocacy for people of trans experience, people living with HIV, and immigrants; and frontline experience serving people of color living with and vulnerable to HIV in the South,” said Jesse Milan, AIDS United president and CEO, in the press release. “As we work to unite our movement and rally the nation behind the defeat of this epidemic, Ms. Chung, Dr. Gipson and Dr. Holtgrave’s powerful voices and expertise will prove invaluable and will add immeasurable strength to AIDS United.”
