Need ideas for your holiday baking this year? Get inspired at this fun baking demo with Chef Tommy of Big City Chefs! Space is limited, registration is recommended. Walk-ins will be accommodated as space permits. About Chef Tommy: Food has been my passion for as long as I can remember! I spent a lot of my childhood helping my mom in the kitchen experimenting with flavors and learning the magic of cooking. By age sixteen, I was working as a busser soaking in the energy of a busy restaurant. Instead of following my culinary dreams, I took a detour and instead went to college to study accounting. I received a Bachelor of Science and cruised through a successful five-year sales career. Despite my successes, I always felt I was meant for something more and decided to pursue my true calling in the restaurant world. I kicked things off as a server in Charleston, SC before moving to San Diego, where I worked my way up to General Manager at Knotty Barrel. Along the way, I enrolled at the Institute of Culinary Education and gained experience working at Michelin-starred Gramercy Tavern in NYC, Trust and as Sous Chef at Sandpiper Wood Fired Grill & Oysters. By December 2024, I was ready to break free from the traditional kitchen grind and launched my own personal chef and catering company. Now, I’m thrilled to be working with Big City Chefs offering catering, cooking classes and more! Whether you’re looking for an unforgettable meal or a hands-on cooking experience, I’m here to take you on a culinary adventure! Coronado Public Library on Facebook / Instagram
