About Us

about us

Started in 1976, the Optimum Health Institute is entering its 38th year. Our 21-day God-centered, holistic healing program consists of three week-long sessions offering classes and activities drawn from 24 ancient spiritual disciplines that promote healing of your body, mind, and spirit. Participants learn to cleanse and nourish the body with diet, fasting, and exercise; quiet and focus the mind with journaling and meditation; and renew and awaken the spirit with study, prayer and celebration. In a safe and sacred environment promoting faith, love and hope, people experience God’s presence in the healing of themselves and others.

The Optimum Health Institute is a healing ministry of the Free Sacred Trinity Church, a faith-based organization rooted in Judeo-Christian doctrine, which states that we are created as holistic beings in body, mind, and spirit. People of all traditions are welcome to participate in our program for mental, physical, spiritual and emotional healing.

The Free Sacred Trinity Church has grown significantly since its inception in 1976 with the development of two missions, Optimum Health Institute of San Diego and Optimum Health Institute of Austin. Since inception, over 150,000 people have attended our missions.
