Glass Onion Catering and Gourmet Foods is a rising force in the pre-packaged grab and go food industry. A trusted source for several top retail brands, Glass Onion was envisioned and created by Tom, a Northern California native. 

Tom Atherstone is a graduate of Cal Poly Pomona with a degree in Hotel Restaurant Management. He has worked with many talented chefs including Wolfgang Puck and Mary Sue Milliken. He served as sous chef at the Beverly Hills Hotel and Polo Lounge, where he learned how to create extraordinary dishes which can be replicated thousands of times without sacrificing quality.

After a move back to San Francisco, Tom accepted a position as sous chef and creative director for Andronico’s Market, where he helped create a catering and gourmet deli program that offered restaurant quality food for cash and carry.

Glass Onion Catering was launched in 1992, as a traditional gourmet catering company for large, high end events and corporate lunch programs.

Retail and grab and go products were launched at the request of steady corporate clients. In 1996, Glass Onion began selling wraps, cookies and salads to well-known, mid-sized southern California retail market chains. Glass Onion still services their stores in California, Nevada, Arizona, Oregon, and Washington with high-quality, grab and go products. 

An expansion of food products and a nationwide contract added quality co-packers to Glass Onion’s availability across the United States. The quality and uniqueness of the food remains high, while the expanded distribution opens new doors to mid-sized and large businesses.
