Hi - I’m Sarah,

Board Certified in Applied Quantum Biology by the American Naturopathic Medical Board & Certified Nutrition Coach by the National Academy of Sports Medicine

 

I am passionate about helping people achieve true health & balance

 

I believe that everyone deserves access to data-driven answers to take their health back into their own hands.

As someone who has struggled with health issues myself, I know how challenging it can be to navigate the overwhelming traditional medical system with little to no results.

My approach involves culling, presenting, and interpreting scientific research and breaking it down into digestible, actionable information to help you live a naturally healthy life.

I specialize in teaching individuals how to retrain the energy management system of their bodies and incorporate proper nutrition to look and feel their absolute best. We go FAR beyond addressing just your food; we’ll take a deep dive into understanding how providing your body with the correct signaling & supporting your mitochondrial health can help you heal and optimize your entire body!
