Our mission

Vital RD helps you navigate through a world of confusing nutrition choices and endless information to pinpoint what works best for your body. We specialize in showing you how to reach your nutrition, health, and fitness goals in a manner that’s accessible, exciting, and sustainable.

Helping clients manage and lose weight, reach peak performance, control a range of health challenges, and accomplish their personal goals continuously inspires us. We prioritize fitting health and fitness into your life, not completely changing your way of being. Shifting your nutritional choices opens up a world of potential - we can’t wait to show you the way.

Primarily virtual in nature, we use the health platform TeleHealth to connect with clients, which allows us to stay in touch in real time, refer to food logs, and have a stream of information to pull from.
