Tamara Keefe.

Tamara Keefe founded Clementine's Naughty and Nice Creamery in 2014, leaving a corporate career to pursue ice cream as a vocation.

Clementine's pioneered a trade-secret process for freezing alcohol into ice cream, producing a 'naughty' line of boozy flavors alongside traditional and vegan 'nice' options. The company has grown to eight retail locations across the Greater St. Louis area plus an online shop shipping nationwide via Goldbelly, and employs over 200 people across its retail footprint and 25,000-square-foot production facility. Keefe was named the 2025 SBA Missouri Small Business Person of the Year. Her flavors have been featured on Oprah's Favorite Things list, CBS This Morning, and Food & Wine Magazine, and Clementine's has twice been named Flavor of the Year by the North American Ice Cream Association - the highest honor in the category. She is a 2018 alum of the Goldman Sachs 10,000 Small Businesses program and a Tory Burch Fellow. Building Clementine's from a single Lafayette Square storefront into a multi-location regional brand with national shipping is one of the more distinctive American food-and-beverage entrepreneurship stories of the past decade.
