Born in 1931 out of the traumatic WWI experiences of Dr. Thurman Fleet, who could not find solutions to his challenges from traditional medicine and theology, what is known today as Concept-Therapy has evolved into a non-profit educational organization. Grounded in philosophical principles that trace back centuries, Concept-Therapy is a unifying correlation of the fundamental disciplines (Science, Metaphysics, Theology, Psychology, Sociology, and Philosophy).
It has been taught continuously at our San Antonio Campus for nearly seven decades, where it has proven itself a viable, workable understanding of living a whole life. Over the course of this remarkable tenure, Concept-Therapy and its related personal growth courses have provided an anchor of support for thousands of people aspiring to a life of health, happiness, peace, and success, and are now taught in locations across the United States and Canada.
Founder
With only a meager formal education and against tremendous odds, Dr. Thurman Fleet was an ordinary man who aspired to the extraordinary. As an infantryman, he earned a battlefield commission from the U. S. Army in World War I and became one of the nation’s most highly decorated soldiers of that conflict. He emerged from the war an “old man” of 23, suffering physically and mentally from the effects of mustard gas and shrapnel in his skull, and haunting, horrific memories plagued the young hero. Army doctors offered him little relief and no hope.
With a family to provide for, he began a fascinating odyssey to rebuild his health and life, taking a holistic approach to wellness. His journey led him into the realms of psychology, philosophy, theology, health, and healing. Thurman Fleet regained his health and attended the Texas Chiropractic College, establishing a highly successful chiropractic clinic in San Antonio, Texas. Dr. Fleet devoted his life to searching for, organizing, and teaching the truth about the human condition in all its complexity. His legacy is Concept-Therapy.
What We Teach Dr. Fleet
San Antonio Educational Center
In 1944, Dr. Thurman Fleet began teaching his philosophy of Concept-Therapy to members of various healing professions, primarily chiropractors. In 1949, he founded the Concept Therapy Institute, a non-profit educational organization in the state of Texas open to all students interested in the study of this philosophy. He purchased the Aum-Sat-Tat Ranch, located in the Texas Hill Country, as a unique destination for study, collaboration, and contemplation.
CTI plays host to instructors delivering Concept-Therapy seminars, area meetings, and conventions. Visitors and guests are welcome at “The Ranch,” and inquiries are accepted at the Concept Therapy Institute Monday through Friday, 9:00 a.m. until 4:00 p.m.
Our Vision
At Concept-Therapy we are building a world where all people are healthy and whole in mind, body and spirit.
Our Mission
Concept-Therapy offers a comprehensive learning opportunity for people aspiring to a life of health, happiness, success and peace.
Robin Brunk-Dawson – PRESIDENT
Robin Brunk-Dawson was introduced to Concept-Therapy in 1982 in Clovis, California, by the Dawson-Harrison Team.

Through the years, Robin held offices in Beam and Pathseeker study clubs and has most recently served as Chief Pilot of the International On-The-Beam Club, an active Board position. Her decades-long studies under legacy teaching teams of the Concept-Therapy philosophy, and a deep personal search for truth, kindled a sincere desire to become a teacher for CTI. Having mentored under her long-time-teacher husband Dr. Bill Dawson after their marriage in 2009, and his teaching partner Dr. Eddie Harrison, The Dawson Team actively presented numerous classes and events at their high-desert Double Triangle Ranch in Weldon, California. They continue to carry the torch by teaching Concept-Therapy and mentoring new teachers.
