Richard P. Deegan & Son Inc was started in 1956 by Richard Deegan. The business offered plumbing and heating services in the areas of Locust Valley, Glen Cove, Sea Cliff and many of the other small towns on the North Shore of Nassau County. The business operated with three employees out of their Locust Valley office but expanded when Richardís son Paul joined the business in 1973. In the late 1970ís, Deegan Plumbing acquired Manhasset Plumbing thus expanding its customer base to the Manhasset and Great Neck areas. Richard Deegan was a past president and member of the Nassau County Board of Plumbing Examiners. Paul Deegan was the past president of the Nassau County Plumbing Heating Cooling Contractors Association (PHCC) as well as the past president of the New York State PHCC. Richard, his son Paul, and son-in-law Richard are all graduates of Mechanics Institute in Manhattan. Presently, the company has three locations and is operated by Richardís son-in-law Richard Scott and daughter Patricia.

Fifty-four years and three generations later, the business is proud to offer the same standards of service and integrity as Richard Deegan did his first day in business.
