Wassertzug, a Rockville, Maryland, resident, started playing hockey after he graduated from the University of Maryland in 1988 and has been a ref for the past 18 years.
"[I enjoy] giving back to the sport, being able to do something so that other people can play, because without refs there can't really be competitive hockey games," Wassertzug said.
