Before accepting the position of Spiritual Leader of Center for Spiritual Living, Tucson, she co-taught at a Montessori school in Tempe. “Rev Rhoni” as she is known here at CSLT, is passionate about teaching the Science of Mind and creating classes for everyone’s spiritual growth.

When not teaching she enjoys exploring Arizona history, traveling domestically with her husband Charles Barfoot and their two dogs, as well as researching philosophical and religious subjects. Her favorite authors are William James, Carl Jung, Laurence Gardner, and Paulo Coelho. One of Rev. Rhoni’s favorite quotes from Ernest Holmes is:

It is only through Love that we find the Presence in its greatness and can use the Power in its fullness.
