I enjoy helping clients who own personal responsibility for their bodies and well being, are not enamored of the idea of medication dependency and who have not been well-helped in the past by traditional medical approaches.
My clients enjoy eating healthful food and learn to do so mindfully. They become experts at managing both their internal and external environments. They understand that food is more than just nourishment, nutrients also send signals to different parts of the body and those signals can be manipulated for optimum health and well-being.

When I work with clients, I like to think that I offer a compassionate and non judgmental environment where we can explore what individual goals might look like and discover barriers to getting there. I focus on building confidence and comfortability at the eating experience instead of fear and anxiety. I use an anti diet, HAES aligned approach. If I help clients learn one thing, I hope that it might be: Fear has no place at the dinner table anymore!

When you work with me, we'll start with a full nutrition assessment, reviewing your diet, lifestyle, medical history, and personal goals.
My ideal client is someone who’s ready for real change but feels stuck. Maybe they’ve tried diets, medications, or programs before, but nothing has worked long-term. They may be struggling with weight, newly diagnosed with type 2 diabetes or prediabetes, or managing chronic issues like high cholesterol or high blood pressure. Many are overwhelmed by conflicting nutrition advice and just want to know what to eat — and how to stick with it. What they really need is a plan that makes sense for their life — not a generic handout or fad diet. They want support from someone who listens, simplifies the process, and keeps them accountable.
