DEHENZEL TRAINING SYSTEMS was created by husband and wife team, Jason and Sophie DeHenzel.  After meeting in NYC while working for a high-end personal training company, they decided it was time to leave the city and opt for a “quieter” life.

Jason and Sophie relocated to Northern Virginia with the goal to couple their entrepreneurial skills with their passion for fitness and for helping people.  In 2012, DeHenzel Training Systems was born.
