WHY does unsolicited nutrition advice seem to pop up everywhere!? If you’re feeling confused about how to truly nourish yourself, you’re not alone. My mission is to create a supportive space where you can reconnect with your body, navigate difficult emotions, and build a sense of self-worth that isn’t tied to food, weight, or athletic performance. Through nutrition counseling, we’ll work together to cut through the noise and address challenges such as disordered eating, emotional eating, fueling for sport, and negative body image so you can find peace with food and confidence in how you care for yourself.

I specialize in medical nutrition therapy for eating disorders, (anorexia, bulimia, binge eating, and ARFID) with a focus on supporting those managing chronic health conditions and neurodivergence such as: ADHD, OCD, Mast Cell Activation Syndrome (MCAS), Dysautonomia, endometriosis, GI disorders (IBS, gastroparesis, SIBO, etc.), and autoimmune diseases.
If you have an eating disorder and a cooccurring autoimmune disease, MCAS, endometriosis, PCOS, or live with neurodivergence such as ADHD or OCD, you might feel that no one understands how complicated this makes navigating food and your body. I want you to know that I’ve walked that path too. I had an eating disorder throughout most of my teens, and shortly after entering recovery, was diagnosed with a chronic illness. That experience decades ago reshaped how I view healing and recovery, and shapes how I support my clients today.
