History

Our founder, Kathy Kudler, was the Vice-President of Marketing for a
large defense contractor. Weary of the constant travel and the pressures
of corporate life, Kathy was looking for other opportunities. As it
happened, Kathy relieved her stress through gourmet cooking and on a
shopping trip for ingredients for a gourmet repast, she suddenly
realized that there was an opportunity for an upscale epicurean food
shop in La Jolla.

Kathy developed a business plan, obtained financing and six months
later, on June 18, 1998, the first Kudler Fine Foods opened. Within nine
months the store was at break-even and was profitable for the year.

In 2000, a second store was opened in Del Mar and in 2003 our third shop
opened in Encinitas.
