In 1984, Stephen G. Hayduk, P.E. opened Hayduk Engineering. Originally formed as a sole proprietorship, Hayduk Engineering was soon incorporated as a professional corporation and later as a limited liability company. Over the course of the next few years, HELLC was molded into a close-knit organization of engineers and technicians which won the respect of its clients, its colleagues in the professions, and regulatory agencies throughout Long Island and New York State, as well as in other nearby states. As a result of the reputation of the firm and of its principal, Mr. Hayduk was also appointed Commissioner of Public Works for Suffolk County, NY, during the 1990's. HELLC serves private and municipal clients providing studies, designs and construction oversight services.
