I have lost a dear brother. Thank you Paula for caring for him so lovingly. He is no longer in pain. But it is hard to let him go. God bless you.
Much love from Kansas City. Wish I could be there! So many memories around the marble board, the boys breaking beds and best of all, Paula, the way he looked at you! You are loved!
Ann, Christopher and family, Craig and family and Kimberlea and family!.
What a great guy Kalvin was, so kind, funny, and talented! He will be greatly missed.
I am going to miss that big smile of his, and all his stories. I could always count on him to buy me a cold Mt Dew. Thanks for the caffeine and all that sugar when I needed it the most.
I love you guys
Paula sending prayers your way. So sorry for your loss.
We were saddened to learn of Kalvin’s death. We were blessed to know Kalvin, Paula, and their family through St. Boniface Church activities and as our children were together at St. Boniface Elementary School. May Kalvin rest in peace, and Paula, Clint, and all who loved him find comfort in remembering a life that meant so much to so many.
Paula and family. I had the privilege of not only knowing Kalvin, but went to school with him (grade school and high school), lived just down the street from him and we considered each other friends. Kalvin and John gave me my first “motorcyle ride” (very short). Kalvin and his family always made me feel welcome in their home. Kalvin will be missed by friends and remembered at our upcoming 60th class reunion. My deepest sympathies to all of you for the loss of a very good husband, father and grandfather.
Dear Paula, Kelly, and Clint, I am so sorry to learn of Kalvin’s death, and also sorry to have learned of it too late to have attended the visitation or the funeral as I would have loved to have given each of you a hug! I remember with fondness our times working together at and for St. Boniface (can anyone say bingo?). My kids’ and my own thoughts and prayers are with you. Kalvin was a great guy who will be sorely missed by all who knew him.
Paula,Kelly, &Clint, we are so sorry to hear of Kalvin passing. We just saw this right now. We will pray for him.
Paula, i am so sorry to hear about Kalvin’s passing. I sure had a lot of laughs with Kalvin over the years and am so glad to have known for so long. He was one special guy that would give the short off his back to help anyone. I sure will miss him. My deepest Condolences to you and the kids.
