 Thelma's founder and CEO, Derek Lewis, said they started at the local farmer's market before seeing the success they now have today. So we started at the downtown farmer's market in spring of 2012 using my great-grandma Thelma's snickerdoodle cookie recipe and a little countertop ice cream machine that my friend loaned me. And we started selling at the farmer's market. Iowa Ag Secretary Mike Nagg said he was particularly proud to highlight a business that is located right nearby in Des Moines.
