Madeline Kallgren is a Registered Dietitian and founder of Marienda Nutrition, a virtual private practice specializing in nutrition for endurance athletes – runners, cyclists, swimmers, and triathletes. She helps clients build fueling strategies that support performance, recovery, and a healthier relationship with food, drawing on her own experience as a runner and triathlete.
Before launching her practice, Madeline spent 5 years at the VA working with Veterans managing chronic diseases, giving her a strong clinical foundation in nutrition’s role in long-term health. She now applies that same evidence-based approach to athletes navigating fueling anxiety, under-fueling, and performance nutrition.
Marienda Nutrition operates virtually, working with clients across the country, and can offer superbills for those seeking insurance reimbursement.
