Fifteen men were the first to pass the exam administered by the New Jersey Department of Conservation and Development and it was those men who on the eve of July 23, 1941 marked the inception of the organization. This group is the conduit to the public through advertising, meetings, sponsorships, Community functions, and consumer mediation.
