I work with clients with disordered eating habits as well as a variety of conditions including binge eating disorder, other eating disorders, diabetes, meal logistics with ADHD or other neurodivergence, prediaebtes, high cholesterol, hyperlipidemia, digestive issues, GERD, and more.
In my practice I use a weight neutral approach with clients. We can work on improving your overall health through nutrition and healing your relationship with food. Instead of focusing on weight loss, we can make reachable goals that are more behavior based.

Hi, I'm Rose! I help people reduce shame and guilt around eating, bring understanding and compassion to eating behaviors, and empower people to make choices around food and their bodies that feel aligned with their life values. There is so much noise about food that it can be hard to actually know how or even what to eat. Nutrition therapy is not only about what you eat, but how you think and feel about about food and eating.
