About TEIA

     The Trefethen Evergreen Improvement Association (TEIA) is located on Peaks Island, one of Casco Bay‚ calendar islands. Peaks is the most accessible island, located approximately one nautical mile from Portland, Maine’s largest city. It’s a twenty minute ferry ride on Casco Bay Lines. The island’s population is approximately one thousand year round residents, but that number can swell to six thousand in July and August. Peaks Island has a long history as a special place to enjoy the beauties of a Maine summer.
