    Shelley started her working life in the Hospitality Industry (that's where she and Gary met!), and eventually left that to teach first grade. When the kids were born, she stayed at home to spend time with them, and started a baking business called Eat Cake. In recent years, she helped Gary manage the paperwork of Harvest Moon and Summer Sun, and joined the effort full-time in late 2016 when they bought the Aire Serv franchise. In her spare time, Shelley likes to read, bake, travel, enjoy time with friends, practice yoga and hang out with Gary and their kids, Clay and Zoe.
