Our Practice
Providing in-person and virtual outpatient nutrition counseling to individuals across Montana since 2020.
Our mission is to provide expert medical nutrition education and guidance in a safe, non-judgmental space.
At Northern Nutrition Group, our dietitians practice from the stance that health can be achieved independent from weight – and that size does not equate to health. People come in all shapes and sizes, and we are here to support the whole you.
The Northern Nutrition Group Philosophy
We recognize there are factors that influence weight beyond diet and exercise. We are also aware of the known connections between weight stigma and discrimination, and the adverse impacts stigma has on the mind and body. Therefore, we use a weight inclusive, non-judgmental, respectful, client-centered approach that supports client autonomy. Our clients receive support in creating goals and identifying internal motivations for behavior change, while receiving current, evidence-based nutrition information, education and guidance.
We support clients from all backgrounds – including but not limited to gender, race, age, socioeconomic status, religious beliefs, sexuality, education level – to provide nutrition recommendations and support that align with each client’s values and culture. Our team of dietitians strive to be culturally competent when providing food recommendations, knowing cultural differences influence when and how we eat.
We also support nutritional health by increasing access to nutrition services in the community, as well as collaborating with providers who offer spiritual, physical, economic, social and emotional well-being resources.
