Lowell, Jim and Loren: My Deepest Sympathy at the loss of your dear Phyllis. We loved her so much. When I think back of all the special times we had during the vending business days with Debbie, Betty, Ida, Joe, mom and dad. Those were definitely the good old days. She will be missed by so many, but I know she will be celebrating a beautiful reunion in Heaven with family and good friends. Her work is done here on earth, and now it is time for her to Rest in Peace for eternity. May God Bless you all during this very difficult time.
