In Memoriam: Thomas Stack

Vertical-transportation consultancy VDA, Inc., announced the passing of industry pioneer Thomas Stack in November 2024. Stack was one of VDA’s original four owners following the purchase from John Van Deusen in 2010. Stack started his career at Central Elevator in 1978, where he quickly became its most skilled and trusted adjuster. His expertise and troubleshooting skills made him an industry leader and a go-to for support, even from competitors. Van Deusen took note of Stack’s special traits and asked him to join VDA in 1989. He accepted the offer and didn’t stop there. Stack was identified early on as one of the next owners of VDA, becoming instrumental in its growth in the existing installation market. Having served on the NYC Elevator Code Advisory Committee, Stack helped shape the local elevator landscape, advising on additions and revisions to city code. At the time of his passing, Stack was the longest-tenured VDA employee, and he will be greatly missed. Former VDA Partner and CEO Mike Smith described Stack as a “truly unique man who I was blessed to call a friend for more than 30 years.” Said Smith: “His humor made you smile, and his brilliance made you think.” Stack’s survivors include his beloved wife of 44 years, Deborah; daughter, Kimberly; siblings, Kathleen, John and Robert; his “furever” friend, Buddy; his “grand-animals,” Daisy, Gracie, Kitty and Ophelia; nieces and nephews; and countless friends. — submitted by VDA
