John F. Sittnick Sr., 91, of Southington, CT, passed away peacefully on Wednesday, May 27, 2026 at the HOCC at New Britain. He was the loving husband of Flora J. (LaReau) Sittnick for 33 years.

John was born in New Haven, CT on March 14, 1935, only son of the late John F. and Mary J. (Callahan) Sittnick.

He worked as a designer and draftsman for most of his working life. John was a man of great faith and a longtime member of The Church of St. Dominic where he was a soloist and member of the choir. He loved acting and singing and was part of local Community Theatres for years. His favorite song to perform was “Rich Man” from Fiddler on the Roof, a musical in which he played the lead role as Tevya. John was a big jokester and an even bigger “punster.” He will be remembered as a loving husband, father and grandfather.
