Recovery Centers of America, which is building a chain of addiction treatment centers from Massachusetts south to Washington,  is holding a jobs fair Saturday with the goal of filling about 20 positions, including intake coordinators, team leaders, and supervisors, the company said Thursday.

The fair is from 9 a.m. to 1 p.m. at 2701 Renaissance Blvd., 4th floor, King of Prussia, Pa., 19406.

Recovery Centers recently purchased a former nursing home in Devon for its fourth facility. It is expected to open in the spring. Locally, additional sites are planned for Blackwood and Paoli.
