The city is inviting local seniors to three open houses at the Rosseti-Cowan Senior Center, 25 Winthrop Ave. The events, free and open to all, are part of a program by the center’s new assistant director, Stephen Fielding, to revitalize the facility by getting more seniors involved. Fielding was hired last month as assistant director of the city’s Office of Elder Affairs and will assume the director’s post next January. The open houses are a chance for residents to catch up with old friends, make new ones, and meet the center’s staff. Attendees will also be able to complete a survey the city will use to help meet the needs of its older residents. Food, entertainment, and door prizes will be featured. The open houses will be held Thursday, on Sept. 26, and on Oct. 24, all at 2 p.m. “It is my hope that these open houses, along with other upcoming initiatives, will work to reengage our senior residents and give them every possible opportunity to get and stay involved in the civic life of our community,” Mayor Dan Rizzo said in a prepared statement.
