It is with great sadness to announce that Saverio “Tony” Caponi passed away on Saturday, May 23, 2026 at the age of 90 years old.
Tony, along with Dave Senften, founded ACSI over 47 years ago. Through their hard work and innovation they propelled ACSI as a pioneer in the development of electrified door hardware products.
Tony’s son Eric (President) and grandson Dominic (customer service) continue the three generations of the Caponi legacy at ACSI.
Tony will be greatly missed by the ACSI Family but never forgotten.

Mark LeGrand

CEO

Ladies and gentlemen, JOHN HOOSS is officially in the building! I did my best to convince him to come out of retirement, but unfortunately for us, he seems to be thoroughly enjoying life, freedom, and having way too much fun.
