Born in Calabria and raised in Chicago, Frank was surrounded by homemade Italian food growing up. After being a Combat Medic for the U.S. Army in the Vietnam War, he moved to San Francisco in 1973 and opened a small sandwich shop called Mr. Submarine in the Marina neighborhood. Mr. Submarine was a success and the business quickly grew to 7 locations. He then got his MBA from University of San Francisco in 1985, at which time, he sold his restaurant chain and, in 1988, officially opened Lettieri & Co. Frank still travels the world, finding hidden culinary gems to bring to the shelves and kitchens of Lettieri & Co.’s customers.
