He worked for Hockers Brick & Tile for over 45 years helping hundreds of couples to design their house and fireplace with brick and stone. He was known as "Mr. Bill" to his customers and many times when Bill and Sue were out to dinner, customers would stop by to tell him how much they still loved the brick on their house after all those years. Bill probably didn't remember their name but always knew the name of their brick. Bill was active in the Brown County Home Builders were he held numerous offices and won several awards. Bill was a huge lover of butterflies. So, Bill and Sue were married in their backyard and as a surprise to Bill, Sue arranged for butterflies to be released by the guests at the end of the ceremony. One of their wedding photos shows a butterfly landing on his lapel. Bill was a kid at heart and loved entertaining people on the many different boats he owned.
