Personal statement: “I believe that anyone – I mean anyone – can overcome any obstacle, may it be physical, mental or any life-altering circumstance that’s before them. God knows we deal with so much in the world we live today. My own life has been a challenge and constant growth.  I’ve dealt with injuries that should have crippled me for life and a loss of a family, both being restored by believing.  I could have either given in to my circumstances and accept a life with self-pity and regret or take a stand and fight back to become the person I was meant to be.  A person who believed anything is possible and nothing could hold me back from reaching my dreams.  So I invite you to make that choice. To believe you can change your life for the better knowing there’s nothing you cannot achieve.  If you are willing to become that person, I challenge you to take this journey.  It will be the best decision you ever made – I promise.  I would be honored to help and show you the true passion behind what I do.”
