Citizens League for Adult Special Services Inc., more commonly known as CLASS, has relocated its secondary program office from North Reading to Wilmington. The move was effective May 19. According to a statement issued by CLASS, an organization that has been serving individuals with intellectual and developmental disabilities since 1976, the new space at Cummings Properties is larger and will help advance the nonprofit’s long-term strategy to increase support services. “We expect more exciting growth during the next five years, and our new space gives the leadership team ample room to increase programs, activities, and support for 85 individuals,” according to a statement released by Bob Harris, president of CLASS. The organization’s headquarters remains in Lawrence.
