Dennis Scully Sr. began his career as an apprentice for well-known Nassau County plumbers. After working for several plumbing and heating companies, Dennis Sr. began thinking of becoming a Long Island plumber on his own, starting his own plumbing and heating company. In 1988, Dennis Sr. created Scully's Plumbing.

It wasn't long before Dennis Jr. took interest. His knowledge of the latest Long Island heating technologies brought Scully’s Plumbing to new levels, thus better serving the plumbing and heating needs of Nassau County.

Danny too soon became interested and started studying the older plumbing and heating systems he saw in so many homes. It is this combination of knowledge that allows Scully’s Plumbing to better serve its Nassau County customers.
