When Bob Koster Sr. founded K&S Plumbing in 1982, he had no idea it would grow into a commercial plumbing company spanning three generations. Once Bob Sr. retired in 1997, his sons Bob Jr. and Jack took over the family business. Today, the company is managed by Brian Koster and Ben Koster with Robert Koster overseeing everything.
