My sympathies to the family in your time of grief.
I was fortunate to have known Isabell when I worked for her at the Main St Steak 'n Shake in the mid-80s. I looked up to her and held a lot of respect for her. She had a wonderful sense of humor and took a photo when I came in to work one Halloween dressed as the district manager,Tom Simpson. How she put up with me, I'll never know - but I'm grateful that she did.
She touched my life and I will always remember her.
