About FSTC

The Free Sacred Trinity Church (FSTC) is a non-denominational, Christian church rooted in Judeo-Christian doctrine. The mission of the Free Sacred Trinity Church is to:

  • Create holistic healing programs to a broken world in need of healing.
  • Commission healing missions such as the Optimum Health Institute to teach the Church’s holistic healing program.
  • Ordain ministers committed to serving God through a ministry of healing.

The Free Sacred Trinity Church believes that by cleansing and detoxifying the body, which is the temple of the Holy Spirit (I Co 6:19), quieting and focusing the mind (Ro 12:2), and practicing spiritual disciplines, one comes into wholeness from the Holy Spirit within. From this point of wholeness, we are prepared to receive the grace of God and heal.

Church Creed

The Free Sacred Trinity Church is a religious organization based on the Judeo-Christian traditions. Through the establishment of Holistic Health Centers, as Missions of the Church, FSTC promotes spiritual and physical healing through the teachings about mind, body, and spiritual beliefs as stated in the Bible. We believe in serving humanity through the teachings of the Father, Son, and Holy Ghost. Within the Church, we follow a way of spiritual growth and development, becoming whole in theological discipline, seeking the Holy Spirit within. We believe that each of the faithful of the church is following a pathway provided by our Heavenly Father. From many different and varied faiths and religious experiences, from all histories and traditions, we learn from one another. We believe that each of the faithful seeks oneness with God. We seek the union of all with the Lord Jesus Christ.

The Five P’s to Optimum Health

OHI’s founders identified five components to optimum health:

  1. Purpose to achieve a natural balance and reconnection to the Divine
  2. Positive mental attitude that supports the healing process
  3. Persistence in following the holistic disciplines of the OHI holistic healing program
  4. Patience with your body and yourself as you allow your body, mind, and spirit to heal
  5. Prayer to a higher source who will share the load with you.

Our Beliefs

We believe that God created humans as holistic beings with an integrated body, mind, and spirit. We believe we can achieve optimum health when the body is purified, the mind is quieted, and the spirit is renewed. From that place of total integration and wholeness, people are then able to strengthen their connection to God, and are transformed to receive optimum health. 

We honor the virtues of love, peace, forgiveness, self-reliance, accountability, and true service. We believe these values enable us to achieve a natural balance, a reconnection to God, and to cross the bridge to our spiritual path.

Our History

Our Founders

Three decades ago, several dedicated people from different traditions were drawn together in unity to help others in their need for healing.

Raychel Solomon met Robert P. Nees, Sr. and his wife Pamela while learning about God-centered mental techniques for healing the whole person. The classes were taught by Robert’s brother, the Rev. Russell Nees an ordained Presbyterian minister. The three learned how to use the mind as a powerful force for physical, mental, emotional and spiritual transformation.

Raychel Solomon, Robert P. Nees, Sr, and his wife Pam Nees founded OHI San Diego in 1976.


Robert P. Nees, Sr, his wife Pam Nees, and Raychel Solomon founded OHI San Diego in 1976.


We believe the Holy Spirit called Raychel, Robert, and Pam to create Hippocrates West – a not-for-profit body, mind, and spirit healing center. The healing program at Hippocrates West combined the mental and spiritual disciplines taught by Rev. Russell Nees with Essene-based dietary and cleansing practices taught at Hippocrates of Boston.

Soon the founders of Hippocrates West recognized the need for a stronger spiritual base in their healing program. As such, they transferred the assets of Hippocrates West to the Free Sacred Trinity Church (FSTC) – a Christian church rooted in Essene traditions. The original healing center became a Mission of FSTC, and its name was changed to the Health Institute of San Diego in 1977. In 1983, the name was changed to the Optimum Health Institute.

Pamela Nees, her husband Robert P. Nees, Sr., and Raychel Solomon founded OHI San Diego in 1976.


Rev. Russell Nees and his wife, Mary Helon, established the OHI Austin mission in 1997.


Currently, the Optimum Health Institute, as the primary healing ministry of FSTC, has helped over 150,000 people. Supporting the Church’s doctrine of unity, and putting biblical truths into action and service, the Optimum Health Institute provide a safe environment for inquirers, adherents, and people of all traditions to heal in body, mind, and spirit at one of its healing centers in the San Diego and Austin areas.
