Suffering from multiple sports injuries, concussions and extreme anxiety, discovering chiropractic care changed his life. Understanding the incredible potential of chiropractic as a natural health care modality and an incredible way to change people’s lives. Chiropractic focuses on making sure the spine is in alignment and thus giving the body it’s best possible chance at healing from within. “I think we often look for outside sources to help us feel better. Most of the time, we are simply chasing the symptoms and not addressing the main cause. By taking the time to focus on the cause, we can formulate a plan to not only help you feel better, but to increase your overall health and wellbeing.”

In his free time, he enjoys golf, rocking climbing, snowboarding and writing. “All I want to do is help people to the best of my ability and chiropractic has provided me with that opportunity.”
