Show notes
Loren Castle started baking cookies after surviving cancer in her early twenties. Five years later, Sweet Loren’s refrigerated cookie dough was generating just $350,000 a year. But instead of giving up, she listened to customers, and reinvented the dough without gluten, dairy, eggs or nuts.  That transformation turned a small regional business into a national brand sold in more than 30,000 stores.
