John graduated from the University of Massachusetts at Boston and now works as a Mortgage Consultant. John says that he regrets not moving to Los Angeles with the Mullen's back in the mid 90's. Their friendship as kids was more of a brotherhood and he hopes that the 'Treasure Hunters' experience will give him a chance to experience that brotherhood again.

They became his brothers growing up, and that brotherhood continues, having grown stronger from the intensity of being a part of "Treasure Hunters." John is very athletic and ultra-competitive. Both he and the Mullen twins are driven, smart and focused. They know their intensity will be their edge in leading them to victory.
