After high school Mary Kay became a dental hygienist. Mary Kay and her husband, Clark served as foster parents to 25 children. For 20 years Mary Kay volunteered and worked with the Boy Scouts of America, achieving the highest award for volunteering. The simplest pleasures in life brought Mary Kay joy. She loved camping. She mastered cooking over a campfire, fishing, and loved sitting in the creek spending time with family and friends. Everyone knew rule #1, don't go camping without Mary Kay; and rule #2…never break rule #1. Mary Kay was a loving mother who always wanted the best for her boys.
Spending time with her family was when Mary Kay was happiest in life. Everyone who knew Mary Kay, knew she was easy going, kind, a great listener, and the best secret keeper.
