Miriam Cervantes is a San Diego native and mother of two children, Azul and Luis. Miriam’s experience working in the foodservice industry began at a young age when she started as a hostess for a restaurant in Old Town, San Diego. While she enjoyed being at the front of the house at the restaurant, she felt as if she was meant to do something more, so at the first opportunity, she took a position working in the kitchen. Miriam worked her way up from dishwasher, to pantry worker, to fryer, and so on, to eventually find her way as a line cook at Casa Bandini. After 2 years, she then moved into the hospitality industry where she worked in fine dining at the Sheraton Hotel for 13 years. Finally, she again changed industries and began her tenure in the healthcare industry at Rady Children’s Hospital for 11 years and now working for UCSD Eating Disorder Center. Miriam is proud of her work because cooking is her passion.
