    I am excited to have the opportunity to work with Fitness Together doing what I do best…helping you reach your health goals! Whether you want to lose weight or gain weight, change your body composition, or leverage nutrition to manage a condition like diabetes or high cholesterol, I am here for you. My style of nutrition coaching is centered around teaching you the skills needed to achieve your goals based on three foundations; evidence-based nutrition, increased physical activity, and changing behavioral patterns and negative self-talk. It is not a diet, rather, it is a systematic, sustainable way of eating that creates vibrant health and lasting lifestyle changes. Helping you learn new skills that incorporate healthy behaviors is my passion and I can’t wait to work with you! Before becoming an RD, I worked as an ACSM-certified personal trainer for over 10 years, so I can attest to the power of exercise and how effective it can be, especially when paired with good nutrition!

    in my free time I like to
    I love to cook and eat delicious food (my favorite food is peanut butter, especially when paired with dark chocolate.) As a matter of fact, I graduated from culinary school! I am an avid exerciser and enjoy weight training as well as cardio (I have run exactly one marathon). I enjoy being outdoors, and my favorite season is spring in Tennessee because I love all the flowers.

    I believe that fitness equals self-love. Loving yourself enough to stick to your goals. Loving yourself enough to take care of your physical well-being for present & future YOU. Fitness encompasses self-love because it forces one to take care of themselves, which in turn provides them with a healthy & flourishing life. Fitness is MUCH more than a physical journey, & I work hard to provide my clients the motivation & encouragement to push themselves when it feels nearly impossible. Ultimately, this discipline, determination, & persistence will lead to long term health & success.

    in my free time I like to
    I enjoy weightlifting, shopping, sunbathing on my balcony, & spending time with family.
