Mission Statement

The primary mission of the Thacher Island Association is to assist in the historic preservation and operation of Thacher and Straitsmouth Islands, two National Historic Landmarks in Rockport, MA. As a 501(c)(3) nonprofit, TIA, which is a fully volunteer-run organization, supports the Thacher & Straitsmouth Islands Town Committee through a variety of fundraising activities including: grant writing, sale of related merchandise, sponsorship of an annual lighthouse cruise, art and photography days, auctions, and coordination of membership fees and donations. 

Goals include:

  • Stimulate interest and facilitate visits to the islands.
  • Raise funds through Association memberships and other sources.
  • Improve and maintain the historic structures.
  • Improve and maintain the scenic trails, picnic and camping areas.
  • Preserve the islands' unique natural and historic attributes.

The ultimate role of TIA is to encourage visitors to enjoy the cultural, historical and scenic benefits that the islands have to offer.
