Hi, I’m MaryAnne Matzen. I’m a Registered Dietitian who specializes in Performance Nutrition for elite athletes.

I received a double Bachelor of Science in Dietetics and Exercise Science from Northwest Missouri State University while I competed in Cross Country and Track & Field for the Bearcats. I also completed my Master’s in Sports Nutrition at Concordia University-Chicago.

While earning my Master’s degree, I served as the Lead MiLB Sports Dietitian for the Miami Marlins for 2 seasons. Prior to the Marlins, I led the Performance Nutrition program for University of Missouri-Kansas City after working for the University of Nebraska-Lincoln Cornhuskers.

I have helped hundreds of athletes of all ages, skill levels, and a wide variety of sports achieve their performance goals through individualized nutrition coaching and education.

I believe Performance Nutrition should be simple and help you as an athlete, not be another challenge on your plate (pun intended). I focus on helping you understand how to fuel your body for your sport and unique needs using evidence-based nutrition recommendations that are easy to apply to your lifestyle.

I offer 1-on-1 Nutrition Coaching, Group Education, Media/PR for Brands, and more!
