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.

I’ve heard the same frustrations again and again: “I don’t feel like myself,” “my moods are all over the place,” “my body is changing and I don’t know why,” or “I’m doing everything I used to, but it’s not working anymore.” These changes are real, and they’re not just “in your head.” My work is about helping women understand what’s happening in their bodies and supporting them with practical, compassionate nutrition and lifestyle strategies that actually fit real life. Guess what, there are over 120 reported symptoms in women who go through perimenopause and post menopause. Yeah, I was just as shocked...
