The National Spiritual Alliance is located in Lake Pleasant, Massachusetts, the oldest continuously existing same-site Spiritualist community in the United States, with roots reaching back to the 1870s. Founded in 1913 by Spiritualist minister and publisher G. Tabor Thompson, TNSA continues to carry forward this living tradition. Our home, the beautiful and historic Thompson Temple, remains a gathering place for spirit communication, healing, and fellowship at the heart of Lake Pleasant’s enduring Spiritualist heritage.
