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."
