Reverend Rhonda Tretsven
Rev. Rhonda Tretsven
Reverend Rhonda “Rhoni” Tretsven brings a lifetime of spiritual exploration, musical expression, and compassionate leadership to her ministry at the Sonoran Desert Center for Spiritual Living.
Born into a metaphysical family, Rev. Rhoni was introduced to the Church of Religious Science at the age of three in Glendale, California. She later attended Founder’s Church of Religious Science in Los Angeles under the spiritual leadership of Dr. William H. D. Hornaday, where she was actively involved in the Junior Choir and church life from an early age.
As a teenager, Rev. Rhoni explored other faith traditions, participating in Presbyterian youth programs and Young Life Bible study, while continuing to express her spirituality through music, guitar, and song. Despite this period of spiritual nomadism, she consistently returned to the Asilomar Conference each summer, reaffirming Science of Mind as the foundation of her belief system. In 2004, while attending Asilomar, she experienced a clear call to ministry and committed to formal ministerial training.
Rev. Rhoni completed her Practitioner studies at Hilltop Center for Spiritual Living in Fallbrook, California, in 2010. She then entered the Holmes Institute of Spiritual Leadership in San Diego, where she continued her ministerial education while serving the Hemet Center for Spiritual Living as Board President and Music Director. She graduated in June 2016, and upon receiving her ministerial license the following month, accepted a letter of call from the Hemet Center for Spiritual Living as its minister. She served the Hemet community for twelve years, guiding the congregation through growth, stability, and spiritual development.
Walking The Path
After completing her ministry in Hemet, Rev. Rhoni entered a new chapter of life, marrying her husband, Charles Barfoot, and relocating to Arizona. While settling into the Arizona lifestyle, she served as a teaching assistant at Meyer Montessori in Tempe and completed her Bachelor of Arts degree at Arizona State University. She graduated Summa Cum Laude with a degree in Religious Studies and a minor in Anthropology, and is a permanent member of the Theta Alpha Kappa National Honor Society for Religious Studies and Theology.
Rev. Rhoni later served for two years with the Center for Spiritual Living Tucson. During her tenure, the congregation experienced significant growth, leading to a shared-campus arrangement with Unity Tucson that expanded CSL Tucson’s presence and operational capacity. As that chapter concluded, Rev. Rhoni felt called to her next ministry, which led her to the Sonoran Desert Center for Spiritual Living.
Rev. Rhoni looks forward to serving the SDCSL community through inspired teaching, spiritual education, and meaningful Sunday experiences that support individual and collective growth. Outside of ministry, she enjoys exploring Arizona history, traveling with her husband and their two dogs, and studying philosophy and comparative religion. Her favorite authors include William James, Carl Jung, Laurence Gardner, and Paulo Coelho.
