Chester and Betsy Kylstra, founders of Restoring the Foundations International, received the revelation of the integrated approach to healing in 1985. They have brought this revelation to churches, networks, businesses and the Body of Christ throughout the world. They have developed extensive training materials and books for this purpose. They oversee the RTF Healing House Network of highly proficient ministers. In 2004, they established the RTF International Training Center to accelerate the release of healing ministers.
