It is with deep sadness that Chaminade High School announces the death of Mr. John Laddomada, a dedicated member of the Chaminade faculty from 2003-2012, where he taught mathematics and gave generously of his time as a moderator of student activities.
John was also a proud member of the Chaminade Family: father of John P. Laddomada ’93, and grandfather of Nicholas ’23, Michael ’26, and Alessandro ’28. His legacy lives on through them and through the countless students he taught and mentored.
