He immigrated to Toronto in 1947 and moved with his family to Winchester in 1957. In his profession as chief mechanical engineer specializing in hydropower, he worked for major global companies in Boston, Denver, Brazil, and Houston. He and Constance returned to Winchester in retirement in 1987, where he was active in several local organizations. Arrangements by Costello Funeral Home of Winchester.
