I have diverse experience in geriatric nutrition, gastrointestinal issues, drug and alcohol addiction/ recovery and other chronic conditions (heart disease and T2DM).
Are you tired of counting calories and monitoring macro intake? Have you tried multiple diets, cleanses and detox programs? Are you tired of trying to lose weight and just keep want to be healthy?At some point, most of us who have tried everything eventually feel drained lost and defeated. We all just want to eat and heal without worry of worsening a health condition or losing control of our weight. I help my clients develop a better relationship with food and their body. They learn how to listen to their body’s needs and eat real food instead of a diet full of manufactured products.

I help with digestion, gut health, women’s health & hormone issues (ie- PCOS), chronic diseases (hypertension, high lipids, liver & metabolic issues), autoimmune disease, and prevention & longevity.
Holistic approach. Food First. Science Based. Using a holistic approach, I assess your diet, symptoms, history, tests to understand what your best next steps would be. We'll work on diet & lifestyle, supplements to fill in gaps, and discuss testing if that is something you want to explore. Imagine what it would be like to be free of your symptoms. Have more energy, mental clarity, normal bowel movements and feel good in your own body. Everyone is different. I use food as nourishment, cell signaling, and healing to get you back to being healthy. I don't have one set protocol for everyone. I offer personalized nutrition guidance.

Emotional eating is a condition that is widely misunderstood. All too often, it is assumed that emotional eaters have no willpower over food or lack the motivation for change. Feelings of guilt, shame, and even loneliness can create a perpetual cycle of dieting and deprivation followed by uncontrolled eating. If this feels familiar to you, I want you to know that you are not alone. I can help you understand this cycle to develop a better relationship with food. I provide education to clear up conflicting nutrition facts, challenge diet myths, and work with you to discover a pattern of eating that supports your health.

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.
