A nonprofit preschool that serves children with autism and other special needs showed off its new Waterville location Thursday during an open house and grand opening.

Woodfords Family Services has moved into a new building on the former Seton Hospital campus on Chase Avenue in Waterville. The 5,100-square-foot school, built by H.E. Callahan Construction Co., of Auburn, replaced its previous and smaller location in Oakland.

Woodfords Family Services, which also operates preschools in Topsham and Westbrook, held a ribbon-cutting ceremony with the Mid-Maine Chamber of Commerce and showed off its classrooms.

Mark Eves, Woodfords’ executive director and a former speaker of the Maine House of Representatives, has said the new 12-room school building with five bathrooms provides enough space for up to 30 children.
