I am so blessed to have had met Diana over 20 years ago at the hospital. Back then I was a vendor selling respiratory equipment and wanted to meet with her. She made me come in to see her at the crack of dawn! We would laugh together about that time and continued our friendship and a special trip to France on the Viking River Cruise with my sister, Lori, her main travel partner and my husband. We had such a lovely time together and will cherish that and the many fond memories of our friendship. Rest in peace, my dear friend. Love you and know you are reunited with the love of your life, Dave.
Diane was a very nice person, smiled all the time. She will be missed. I knew Diane for a long time. I works in the same hospital for 42 years also & her sister in radiology. My thoughts and prayers go with you and her family.
I knew Diana for over 25 years. She the sweetest, always smiling and had the tinkle in her eyes when she married Dave. Diana you knew I loved, when you asked me to make rolled stuffed pizelles for your wedding! We did do a lot of things together that I will not forget. You can now Rest In Peace. May the Lord keep your family in a hug and help them through this of grief
