Bruce Weiss, the chief executive officer of Test Positive Aware Network (TPAN), resigned from his position July 6 after 15 months on the job. He was replaced by TPAN Director of Client Services Bill Farrand, who will fill the position while the organization’s board of directors seeks a permanent replacement for Weiss.

Although Weiss did not respond to a request for comment, Farrand described his departure as “very amicable,” saying that it was Weiss’ decision.

In a press release, TPAN Board President Tom Hart said, “Bruce arrived at a time when TPAN, like many other organizations, was struggling with the effects of the downturn in the U.S. economy and reduced funding, and helped to provide stability as well as to improve infrastructure at the agency when it was needed.”

Weiss joined TPAN in March 2009 after having served as director of community health for Washington, D.C.’s Whitman-Walker Clinic. Prior to that, he was director of the Whitman-Walker Clinic of Northern Virginia, and served as executive director for the Washington, D.C.-based Sexual Minority Youth Assistance League.

TPAN, a 23-year-old organization located on the city’s North Side, offers support services and programming for people living with HIV and AIDS. It also publishes the bimonthly magazine Positively Aware, which addresses HIV treatment and wellness.

Farrand’s tenure as interim CEO will be his second: He served in that position temporarily prior to Weiss’ hiring. Farrand, whose degree is in community counseling, has worked for the organization since 2007.
