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.

Do you struggle with restrictive nutrition advice, food guilt, or feeling like you’re “doing nutrition wrong”? Have you spent a lot of time trying to follow rules that don’t fit your life, culture, or body? I’m best suited for people seeking flexible, realistic support for cancer prevention or survivorship, chronic conditions (like CKD, diabetes, GI disorders), eating disorders, or women’s health and hormone transitions—who want sustainable change and a more supportive relationship with food.

With years of experience in the eating disorder field, alongside deep dives into sports nutrition and clinical research, I blend science with a human-centered approach (and a good dose of real-life practicality).
My approach is compassionate, evidence-based, and grounded in the belief that all bodies are worthy of care. I’ve worked in a wide range of settings - from treatment centers and university athletics to labs and lecture halls - which gives me a unique lens on how nutrition, psychology, and performance intersect.
