My deepest condolences to the Halfhill family. I worked with Joan for many years. We had the same job titles but I was in Andover and she in Cincinnati. Joan was the kindest, thoughtful, and most genuine lady I ever had the pleasure to work with. When I visited the Service Center she would take me to a favorite local restaurant or out to tour the sites. She was not just a co worker; she was a friend. And how she loved her family. Her face lit up when she told me about her grandchildren. May her memory be a blessing.
