Mark O'brien

NInjastics Director

Coach Mark, a six-time ninja world finalist, was first introduced to Let It Shine in 2015 during a Ninja Clinic hosted by LIS. His love for American Ninja Warrior inspired him to start taking ninja classes and competing in ninja competitions across the US. In addition to his ninja accomplishments, Mark recently completed his first full Ironman triathlon race after two years in the sport.

Mark began coaching at Let It Shine in 2016 and has since become a valued member of the LIS community, known for bringing fun and confidence to the kids he coaches.
