Kate practices out of Health Loft providing nutrition therapy for adults and adolescents with Disordered Eating, Eating Disorders, Intuitive Eating, Vegan/Vegetarian diets, and other conditions. Kates drive as a dietitian is to work uniquely with each client to create safe, sustainable, and nourishing relationships with food. I believe that qualified and unbiased nutrition care should be available to every individual, no matter their size, health barriers, or schedule. I translate my culinary training into my practice by promoting food as not only a source of fuel, but comfort, tradition, celebration, connection, and recovery.

Hi! My name is Kelsey and I’ve been a Registered Dietitian since 2014, licensed in the state of Illinois. I’ve always had an interest in food, which started in childhood. I was a very picky eater (sorry mom and dad!), and decided early on that I would be a vegetarian. As I’ve gotten older, I have expanded my food palate, but I’ve always stuck with the morals of eating foods that help me feel good and I believe that is a guiding principle of overall health.
