    Sending prayers for peace and comfort to all who were blessed to have known Dennis. Although I had only just met Dennis and only had just a short time to get to know him, I am so glad I did. His personality was big, his kindness as big, a smile I’ll never forget. Many fun memories we had in the short time I had with him for sure. He is greatly missed and forever has a special place in my heart. Thank you for allowing me and trusting in me to care for Dennis! So sorry….
    I’ll see you again Dennis!
