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.

Today, Larry III has joined the Silvi Materials brand to work alongside his father and uncle to continue pushing the business towards excellence.
