    Chuck and I want to send our sincere condolences. Dianne was a true friend and will be surely missed. We had many enjoyable years of playing bingo together, always enjoyed her company during our phone visits and “oh could she bake.” Now Dianne has been called to become an angel and although she is gone, she will never be forgotten.
    Chuck and Lorraine Phelps
