Welcome to MSA Group

MSA Group started as MSA Construction back in 1989 by the late Carlo Valentini. Formerly a Councilor with the City of Canning, Registered Builder and Designer, Carlo retired in 2007 and in honour of what he taught me and the reputation he built his business on, I have maintained the MSA name.
