Patrick H. Mackay was born on his grandfather's 500+ acre estate, "Harbor Hill." His family sold the property, which is now the village of East Hills and moved to Locust Valley in the mid fifties. Patrick went to Green Vale School, boarding school and college, and then decided to move back to Locust Valley. He became a licensed agent at Piping Rock Associates in 1972 and purchased the firm in 1976 when he was 27 years old.

Since acquiring the company, Patrick has been involved in the acquisition of other high quality real estate firms with the intention of blending their agents into the Piping Rock mold. He has been extremely successful in matching personalities of agents with buyers and sellers, and also with having the agents remain at the firm during increasingly competitive times.

Patrick is deeply involved in the community, and over the years has been on the boards of numerous charities, various boys and girls clubs, a Brooklyn Charter school, local country clubs, as well as Christie's Internal Real Estate.
