My ideal client is an individual or parent seeking to learn more about their food allergy diagnosis, diagnosis related to abnormal gut function. If they have an eating disorder, they are ready to learn how to move past it and repair their relationship with themselves and their food. My clients understand that slow changes are lasting changes are not interested in a quick fix. They are comfortable with my approach that all foods can fit into the eating pattern and health looks a lot of different ways.

I work with clients who feel overwhelmed by chronic symptoms such as fatigue, pain, digestive concerns, hormone changes, brain fog, or metabolic issues. Many have been told their labs are “normal” but still do not feel well. They are looking for clarity, structure, and a plan that makes sense. Many want to improve their health but feel uncertain where to begin or worry they may not be successful. They are seeking guidance and a thoughtful partnership to help them move forward.
