The Team

Dr. Jon Parsons

At age 45 program creator Dr. Parsons had a wake-up call, finding himself overweight, consuming excess amounts of alcohol, and having to stay home while his wife exercised, he was fed up. In pain, fat, and frustrated Dr. Parsons set out to reverse the course of his life. Through meditation, education, research, and personal experiences in the very same TEMPL program, Dr. Parsons saved his life and began to stop all of the effects of premature aging he had been experiencing. ...

Now at age 51, Dr. Parsons is enjoying his grandchildren and loves having a friendship with his adult children. Being physically able to exercise and embark on outdoor activities free of pain is truly something he will not put a price tag on.

Dr. Parsons holds an undergraduate degree in exercise sciences and sports performance, a masters degree in education, and a doctorate in education leadership. He began teaching and coaching in 1991. He has coached at every level of athletic competition. He has counseled and worked with countless individuals to navigate through the stresses of living in a modern world. Dr. Parsons resides in Tucson with his wife Christa.
