Camp Chesterfield offers Spiritualist Church services, seminary, and mediumship, faith healing, and spiritual development classes, as well as psychic readings for patrons.

[5]: 96–97 Well-known writer on paranormal topics Allen Spraggett visited the camp in 1965, and was unconvinced by the spirit materializations during seances: In 1976, M. Lamar Keene, a former medium in Florida and at Camp Chesterfield, confessed to defrauding the public in his book The Psychic Mafia "as told to" Allen Spragett.

In the text Spragett and Keene detailed a multitude of common techniques utilized by fraudulent mediums since the 19th century to conjure spirits.

The pieces of paper are not returned to the parishioners; rather, Spragett and Keene wrote, the data is shared freely amongst Camp Chesterfield mediums as well as those networked across the country for use in private hot readings.

As the movement gained in significance at the turn of the century, permanent buildings were added including a church, meeting house, and homes.

The last major development phase of the camp occurred after World War II, including a 1949 hotel, 1954 cathedral, and a 1958 art gallery.
