A longtime HIV organization celebrated its anniversary on Sunday, toasting its supporters and raising funds to continue and expand its services next year. 

Party With Impact marked another year of work by Positive Impact Health Centers, which serves people with HIV with offices in Midtown and Duluth. It's an annual shindig that this year moved to the Center for Civil & Human Rights in downtown Atlanta.

The event was billed as the organization's 25th anniversary celebration. 

Positive Impact launched in 1993, three years after AID Gwinnett did so in 1990. (AID Gwinnett was officially incorporated in 1991.) The two organizations merged in 2015 to create Positive Impact Health Centers with a $6.5 million budget, nearly 100 staff members and more than 300 volunteers providing HIV care to more than 9,000 clients each year.
