Coastal Senior College, which offers classes to Lincoln and Knox County citizens 50 years and older, will celebrate its 10th anniversary on Thursday, Sept. 15 from 4 to 6 p.m. at Thomaston Academy, its original home.

CSC began in the summer of 2001 when a steering committee was formed through the University of Maine at Thomaston (now located in Rockland). The first classes began in the spring of 2002 to 141 members. CSC now has 350 members and offers about 20 eight-week courses in the spring and fall as well as some shorter courses in the winter. Classrooms are located in Camden, Rockland, Damariscotta, Waldoboro, Thomaston and Boothbay.

Rabbi Harry Sky of Portland originated the idea of a senior college network in Maine when he discovered there were unused classrooms during part of the week at the University of Southern Maine. He placed an ad in the Portland Press Herald and 500 seniors showed up. In 1999 he sought funds from then-Governor Angus King, who set aside $150,000 the following year. There are now 17 senior colleges from Fort Kent to Wells and Machias to Bethel, and upwards of 5,000 active members.

The celebration will feature live music, refreshments, slides and presentations by founders, including David Bailey of Newcastle. Thomaston Academy is on Route 1 in Thomaston. Call 1-800-286-1594 for more information and to make a reservation.
