Jan lives in Berian Springs, Michigan. He builds and repairs guitars there. He used to be a good friend when he was in Chicago and married to Anne Hills. He repaired my Martin D-76 (9-string) when I had it in a soft case and it was crushed by the lid of a storage compartment on the steamboat Julia Belle Swain. Jan did a wonderful job of restoration on the top, sides and back. His own guitars are beautiful. Annie Hills still plays them most of the time. For years Jan made them with the name DOVE. These days Jan is a very private person.Art Thieme
