CrossFit coach and owner Kerrie Olsen underwent surgery on Monday, May 11, after suffering a traumatic brain injury in a golf cart crash while vacationing in Mexico. Olsen was forced to have a piece of her skull reconstructed with a custom ceramic piece after the original part of her skull was not a match for reattachment. "Everything went absolutely perfect and the connection was perfect," Olsen's sister, Heidi Gustavson, shared via Facebook on Monday.
