About Us

The Faithful Brain Institute, LLC was established to provide resources, training and support for those seeking to experience life to its fullest.  We believe, and science affirms, that Jesus’ life, character and teaching provides a guide to truly and fully experiencing human life.

In Your Faithful Brain, Dr. Matheson describes a “faithful brain” as a brain that “is fully integrated with God, within itself and with others, optimizing its design.” A person with a faithful brain is fully experiencing human life.

The Faithful Brain Research Foundation is a nonprofit organization established to conduct and support research on the relationships of brain design, Christian faith, character and quality-of-life and the efficacy of Christian psychotherapy.
