Meet Our Dietitians
Mary Beth Russell, RD, LN, CDE
I have 18 years of experience developing others into the healthy person they want to be. I absolutely love my job. I am passionate about my own personal mission for health and wellness and feel it is the key to a long and happy life. I also feel very strongly about the benefits of exercise. I spend a great deal of our free time at the gym working out. In my opinion, a well balanced diet needs to be partnered with a well balanced workout that includes both cardio and weight bearing exercise for overall health. As a registered dietitian I feel it is my mission to meet people where they are at in their wellness journey. I enjoy partnering with them to develop their own personal health goals and then my aim is fulfilled as I guide them on their path to success.
Lauren Cornay, RD, LN
Food plays an important role in everyone's life; impacting our health, evoking emotion as well as affecting budget. I pursued a career in dietetics to help members of my community develop eating and lifestyle habits that not only optimize their health but also allow them to enjoy what they eat. My passions for cooking, baking and physical activity serve me well in my role as a dietitian. I obtained my undergraduate degree at South Dakota State University and completed my dietetic internship at the University of Nebraska Medical Center. I spent four years at Genesis HealthCare Systems in Zanesville, Ohio working primarily in the critical care unit, managing nutrition support. Joining the Avera Heart Hospital team provides me the opportunity to work closely with patients and their families to make the diet and lifestyle changes that can save lives.
