As Operations Director, Mecaela manages operations and logistics for Mentis including IT, facilities, and offsite housing properties. Prior to joining the Mentis team, Mecaela owned a business called Rooted Fork that had two main prongs (yes, pun intended), offering guided walking food tours in downtown Napa and event planning for large scale affairs including BottleRock, the Napa Valley Film Festival, and many more. Between her prior work experience, a bachelor’s degree in Wine & Viticulture from Cal Poly San Luis Obispo, and a master’s degree in psychology from Arizona State University, Mecaela is intimately familiar with Napa Valley and is an ideal fit for the role of Operations Director. Outside of work she enjoys reading, Pilates, gardening, and cooking, so much so that she once took a semester off from college to cook in a professional kitchen. But her greatest passion in life is family and she relishes spending time with her husband, daughter, and dog.
