David graduated from the Holy Cross College in 1975 and entered the HVAC industry in February 1982 where he worked for a subsidiary of Brooklyn Union Gas, GEI, that had a relationship/partnership with Hitachi Absorption Air conditioning. York bought the Hitachi rights in 1991, asking David to join the team. With over a 31 year run, David is proud to be keeping the tradition together at Gil-bar. David even piloted destroyers in the U.S. Navy for six years, trading in his destroyer for a sailboat after leaving the navy, a hobby he still keeps up today.
