Marilyn Leo has been part of Religious Science since childhood. She has worked in the Religious Science Archives for twenty years, including creating the Archives and Library Foundation that houses all archival information for Centers for Spiritual Living. She serves on the Board of Trustees for the Hefferlin Foundation, an independent nonprofit foundation supporting the teaching of Science of Mind. She has written a number of books, including an exhaustive history entitled "Chronicles of Religious Science," Volumes I and II. She says writing the story of Anna Holmes has been both an informative and a delightful journey. As a young girl, she knew Anna and, of course, always called her "Mother Holmes."
