Dr. Robertson received his medical degree from University of Arizona in 1985.  He was board certified in Family Practice and practiced medicine in Gilbert, Arizona.  A motor vehicle accident in 2002 left him disabled and ended his medical career.  His transition to a simpler lifestyle was facilitated by spritual study, prayer, and meditation.  The combination of his scientific background with his understanding of spiritual priciples allows him to synthesize divergent belief systems into universal truth.  He spent his medical career explaining complex health problems to his patients in understandable terms.  His ability to clearly illustrate difficult concepts is demonstrated in his first book on personal spirituality.
