Mission Statement

Community Description

Adelphi is an intentional community founded by the author of the book “The Ultimate Frontier.” It is a place for those people interested in the philosophy presented in that book to live and interact with others of like mind. The book gives an intelligent explanation of the mysteries of human existence, and provides a practical approach to spiritual growth. Many readers said it tied together the many pieces of their own philosophy they had already learned through living. The book’s philosophy is centered on the idea that the purpose of life is personal growth in psychological and emotional maturity. The pursuit of ever-greater maturity is a continuous challenge with great rewards, and it is the ultimate frontier.
Learning about the community and becoming a member and resident begins with reading “The Ultimate Frontier.” Adelphi is a place where conscious, deliberate effort to achieve ever-greater maturity is our purpose, and members work to create a culture that supports that goal. Come live, learn, and grow with us.
