Nancy’s “Why”

Nancy loves to “problem solve” which explains her continued interest in practicing law and in her hobbies of reading (history and English mysteries), gourmet cooking, and aspirational golfing. Last fall Nancy and her husband took a tour of World War II battlefields sponsored by the National World War II Museum and hope more travel is in their future.
