I can review functional test results or recommend one.
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.

My specialty is trauma informed, functional nutrition for mental health, digestion, and hormones.
My ideal client has done everything right, followed plans, taken supplements, read the books, but still feels anxious, exhausted, or disconnected from their body. They often struggle with digestion, hormones, or stress related symptoms and want to understand why. They are ready for a compassionate, science based approach that honors both body and mind. Together, we restore a sense of safety first so energy, digestion, and calm can follow naturally.

Do you suffer from symptoms related to food sensitivities, but are unable to pinpoint exactly how or which foods? Do you have chronic health conditions related to inflammation, such as IBS, Migraines, Fibromyalgia, Rheumatoid Arthritis, Colitis, or others? Your everyday foods can often provoke these conditions. As a Registered & Licensed Dietitian who is also a Certified LEAP Therapist, I use the MRT lab-assisted elimination diet to help treat your symptoms related to food intolerances. Having worked in OB/Gyne for 20+ years, I also specialize in all aspects of women's health, from pregnancy to menopause and more.

If you’ve been dealing with ongoing gut issues, hormone changes, or chronic symptoms and feel like you’re not getting real answers, you’re not alone—and you’re not imagining it. Clients often come to me feeling dismissed, overwhelmed, or stuck—and leave with clarity, direction, and a deeper understanding of their body. If you’re ready to stop guessing and start feeling better, I’d love to support you.

Do you have an unhealthy relationship with food? Do you get stressed thinking about what to eat? Have you tried different ways of eating to help you feel better and nothing seems to work? Like you, I struggled. I have ADHD, Thyroid Disease, and had disordered eating patterns for many years. I help people identify the root cause of their illness and incorporate nutritional changes. I know what it's like to have a negative body image and be exhausted from thinking about what I could and couldn't eat. Food should bring joy and satisfaction, not stress.
