Dr. Grewal grew up in Surrey, BC, playing several different sports while growing up, eventually going on to play college basketball. His body, however, was riddled with different injuries and illnesses over the years. These traumas limited his progression with basketball and reduced the joy of playing at an elite level. Fascinated with his injuries he decided to pursue a Bachelors Degree in Human Kinetics at the University of British Columbia with a specialization in Clinical Sciences. He then travelled to California and completed his Doctorate in Chiropractic from Life Chiropractic College West.
