Memories Timeline


  1. My first hero and best teacher; you always had a different viewpoint to offer which led us to grow. You will be sorely missed. Rest with the angels, Dad.

  2. My thoughts and prayers are with all of the McCallister Family. I worked for years with Tom (Mac) at US Bank. I actually sat right next to him. He was fun and great to work with. I am truly sorry for your loss. I hope the memories you hold dear to your hearts bring you comfort. With sincere sympathy, Sue Wolf
