Predeceased by his loving parents Margaret (Gilroy) and Patrick Armstrong, John is survived by his devoted sisters, Helen Lenahan (David) and Catherine Gallucci and his brother Thomas Armstrong (Kate).

He is also predeceased by his dear brother-in-law William Gallucci, and beloved nephews Lawrence Lenahan and Timothy Armstrong.
John was born in New York, New York. He graduated from Saint Helena High School (now Monsignor Scanlan High School) in 1971 and then achieved academic success at Marist College graduating in 1975. John served in the New York National Guard.
John had a successful career in the hospitality industry owning restaurants and nightclubs in Manhattan. Casey’s Dance Hall and Saloon was so popular lines formed around the block just to get into this hot spot! A trailblazer, he established Yorkville and Carnegie Hill Breweries in the early 90’s which were among the first microbreweries in Manhattan.
He also was an entrepreneur in real estate, developing commercial and residential properties on the east end of Long Island.
Mostly though, John was a beloved son, brother, uncle, great uncle and friend. Affectionately known as Uncle John to family and friends alike, John brought people together. Whether it was at Casey’s in New York City, in Saratoga, or his home in Westhampton Beach, John loved having his family and friends around and was always the most generous host. We all share wonderful memories of summer Masses celebrated by the late Father Pete (Colapietro) at John’s home followed by libations and gourmet meals—parties that often went until the wee hours with the sounds of Donna Summer, Neil Diamond and Frank Sinatra filling the air.
He cherished dinner with friends, a day at the racetrack cheering on his horses, and reading and relaxing on the beach. John will be missed greatly. We will forever hold him in our hearts and his legacy will live on always.
Visitation will be from 2:00 to 7:00 pm on Sunday, April 2 at Werner Rothwell Funeral Home, 60 Mill Road, Westhampton Beach, NY.
A Mass celebrating John’s life and faith will be held on Monday, April 3 at 11:30 at Immaculate Conception Church, 580 Main Street, Westhampton Beach, NY.
The Interment will be private. In lieu of flowers, donations may be made to Monsignor Scanlan High School or Marist College.
