Madeline Kallgren, RDN, is the founder of Marienda Nutrition LLC, a virtual nutrition practice offering compassionate, non-diet nutrition care for adults. She helps clients manage chronic conditions like diabetes, high blood pressure, and high cholesterol, improve digestive health, and build a more peaceful relationship with food. Sports nutrition is a particular specialty, and she supports everyone from weekend walkers to competitive athletes.

Madeline spent five years as a clinical dietitian at the VA, working with Veterans managing chronic diseases, which gave her a strong foundation in medical nutrition therapy. Her approach is weight-inclusive and practical, focused on how food helps you feel and function rather than on the scale.

Marienda Nutrition is in-network with BCBS of Illinois PPO plans. Sessions are held virtually in Illinois and select other states, and superbills are available for other plans.
