Strong Family Values

Since its inception in 1947, Silvi has been a family-owned business that has grown and expanded with each new generation of Silvi leadership. Larry Sr. launched the concrete business while still working as a butcher in his family’s general store by day. In the 70s, his sons John and Larry Jr. joined the company after earning their degrees from Syracuse University. Today, Larry III has joined the Silvi Materials brand to work alongside his father and uncle to continue pushing the business towards excellence.
