Meet Rosa Keller PhD, RD

As a nutrition scientist and dietitian, I have always been curious about the human body and our relationship with food. Today, we live in a world with so many mixed messages about what we should or shouldn’t eat. My goal is to help you develop a strong understanding of food and nutrition, based on current evidence-based research, so that you can make empowering decisions about the food you eat.

I earned my PhD in Nutrition Science from Oregon State University, where I conducted nutrition research focused on the benefits of vegetables for exercise performance and cardiovascular health. I learned to critically evaluate nutrition literature, and taught nutrition and fitness-related courses throughout my 8 years there. I completed my dietetic training at UC San Francisco, where I counseled both adult and pediatric patients with varying nutrition needs.

I understand that food is a very cultural and social component of our daily lives. Food is meant to be enjoyed and celebrated. I combine my expertise as a scientist, athlete, dietitian, chef and teacher to help you reach your nutrition goals while also keeping into consideration your cultural values and social schedule. Whether that means learning more about the fundamentals of nutrition science, improving your relationship with food, or fueling your exercise, I am here to help.
