Kathy always put up with all of my questions and when our daughter passed away she was the one who took us to St.Joseph’s cemetery to decide on a gravesite. Her kindness made that experience so much more bearable for us. We will always be grateful for being blessed to have known her. God bless her sweet soul

I'm so saddened by the loss of Kathy. Her and I go back a long way to Jaycees days. We played cards together and of course we had ties to church as well. This is a huge loss to our whole community. She was such a kind and gentle soul. She will be greatly missed. My very deepest sympathy to David and family.

My condolence to David, uncle Ray and the Siberz family for your loss. I remember her mother and dad bringing her to Sunday morning church in a white dress with a bow in her hair at Durwards Glen. Will always remember Kathy like that, in her pure white dress again, as she is embraced by her Mother and Father in heaven.
