I have dedicated much of my time studying and 
researching -- attempting to make sense of everything. My goal is always to give people hope when 
they feel there is none. My research has a direct compassion attached to it (with a lot of sympathy), 
while always attempting to find the hidden truth behind all of the chaos.

More about Sean...

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.
