One of Guam’s MMA pioneers has suddenly passed this week.
John Crisostomo died of a heart attack while back home on Guam.
Crisostomo fought from 1999-2006 under promotions such as Super Brawl, Pancrase and Fury – in the tournament days where a win brings you back for another fight that same night. He finished with a career record of 8-9.
He was 52.
