Catherine's food career began when she took a job bussing tables her freshman year at the University of New Hampshire. After graduation, she launched a personal chef business and began working her way towards a Master’s in Gastronomy at Boston University.

Catherine’s writing has appeared in The Boston Globe, Saveur, Departures and Serious Eats; she is a recipient of The Les Dames Escoffier Legacy Award for food writing. She is a former cast member of the Emmy-winning TV show Christopher Kimball's Milk Street, and former contributor to Milk Street Radio. She also co-hosted two seasons of a podcast for The Food Lens, a Boston-based food publication.

Currently, Catherine is host of the podcast Talking to Smart People, and author of the weekly recipe newsletter Smart Cooks on Substack. She is also a co-founder of the nationally distributed sauce and dressing brand, not just co.

Catherine lives in Somerville, Massachussets with her husband Artie, their sons Jack and Pete, and their rascally black lab Clementine.
