She graduated from Purdue University where she interned under the Director of Sports Nutrition, serving and educating Purdue athletes for 2 years.

Through individualized nutrition coaching, she provides programming designed to meet you where you are at and guide you to where you want to be, building better habits and learning nutrition fundamentals along the way. You won't simply be given a cookie-cutter plan, but one designed with you, to fit your unique needs, lifestyle, preferences, and goals that will help you create results that last after the program ends.


Let's get to work!


MooseFit Nutrition Coach - Registered Dietitian

"As a Registered Dietitian, I have a true passion for nutrition and wellness, and love working with individuals to help them reach their nutrition goals. My passion for health & fitness grew even more when I joined a local gym 3.5 years ago. Once I discovered how good exercise and heavy lifting could make me feel, and how much energy it gave me, I was hooked. Now, that same energy fuels my passion for health and nutrition and I can't wait to share that passion with you!

As a health & wellness enthusiast, I truly believe that eating well is a form of self respect - and I'm here to help you achieve your goals one healthy change at a time! It's important to eat whole, real foods and build a healthy relationship with food. When I'm not providing nutrition consultations with MooseFit clients, you can find me working as a Registered Dietitian consultant with Girls Got Goals and a Clinical Dietitian at Sacred Heart Hospital, or enjoying sushi with my husband."
