The father of holistic medicine.

Dr. Herman Aaftink organized New Thought Seminars in the Canadian Rockies in Banff, Alberta. Outstanding New Thought authors’ participated such as Emma Smiley, Jack and Cornelia Addington, Joseph Murphy, Jack Holland, Sig and Janie Paulson, Johnnie Coleman to name a few.
 A dynamic young lady from Edmonton, Alberta named Jaclyn Darby attended one of the early seminars and heard the spiritual call to start the Church of Truth work in Edmonton. Both Calgary and Edmonton centres flourished and became the Life Enrichment Centres, spiritual hub of the Canadian Churches of Truth.  Dr. Jaclyn Darby and Dr. Herman Aaftink have served as teachers, healers, speakers, coaching and training and as a result there are today a wide variety of New Thought centres and churches in Canada.

Sig and Janie Paulson were Unity ministers who have traveled around the world giving lectures and workshops on the spiritual approach to healing.

Evarts Greene Loomis (1910–2003) was an internationally known homeopathic physician, surgeon, author, lecturer, and visionary who is regarded by some as "the father of holistic medicine," Loomis preferred to be called Evarts rather than "doctor".
Evarts, with Rev. J. Sig Paulson, authored one of the first books on holistic medicine, Healing for Everyone: Medicine of the Whole Person
