Sam Lopez, Registered Dietitian

Growing up in the food industry from a young age, Samantha had instilled in her a passion for nutrition.  After completing her undergraduate in nutrition from Texas A&M University (Whoop!), she worked in the elementary public school system for a year and half. Eager for more education she attended Texas Women’s University to obtain her master’s in nutrition and food science. Once completed she landed a job as a nutrition culinary instructor with Wellspring Camp/Academy where she assessed, counseled and taught skills to people ranging in ages from 8-50+. She also led multiple workshops and seminars for clientele. For two years, through Wellspring she lived and worked in North Carolina and California, in turn able to enrich other’s lives through healthy eating. She was featured on multiple media outlets that captured healthy cooking and eating habits. Samantha was then presented with an opportunity to complete her dietetic internship through Tulane University where she worked with patients in a variety of dietetic fields. Keen on imparting her love for food and healthy eating she found Jan Tilley and Associates where she willingly jumped on board. She is enthusiastic about meeting new clients and helping them to achieve their healthy lifestyle goals!
