"At the ripe old age of 16 I was almost bedridden with back pain to which the back specialist finally gave me a diagnosis of degenerative disc disease where seven of my discs were over halfway gone. He said my back was the equivalent to an 80 year old's.
This is where my passion comes in. I have spent my life researching and helping others prevent pain while accomplishing goals they never dreamed were still possible.
I was told no matter what I did that I would be paralyzed from the neck down by the age of 30. I am now 36 without pain most of the time all without medication or surgeries.
This has given me the passion and the knowledge needed to help people get to their goals even when they first believe it isn't possible anymore."

The love of martial arts led Lee towards the field of personal training. Successfully navigating through multiple disciplines helped Lee realize that no matter how much skill he achieved, that there was a physical aspect that the martial arts world couldn't offer... one that he knew could propel him even further.
With the help of his trainers, he achieved a much stronger stature. Now that he has unlocked his potential, he wants to help others do the same. His excited personality will help you keep accountable, and love every minute of it!

"My passion for fitness started in high school where I trained in competitive karate. As I progressed through the ranks I started training the newer students; giving me my first taste of personal training.
After high school I got into running which eventually evolved into a passion for doing triathlons. I became interested in exercise of all kinds and decided to venture into it as a career.
Besides being a personal trainer I’m also a freelance video producer, cinephile, tabletop gamer, and all around nerd."
