Hi, my name is Rebecca, and I am so glad you stopped by! As a functional medicine nutritionist, I believe that everyone should have the opportunity to experience true wellness.

My Story

Some years ago, I struggled with a neurological condition known as cervical dystonia. Constantly fighting against my spasming neck muscles was challenging and embarrassing. Painful medical treatments only partially and temporarily eased the symptoms. On top of that, the cost was astronomical! So, I set out on a quest to address my own health issues and have been symptom free for over 6 years now! From my own experience, I have gained a deep empathy for my patients’ health struggles, and a great passion for helping them get back to the lifestyle they once enjoyed!

My Experience

For nearly 10 years, I have successfully worked in private practice with those who struggle with a myriad of chronic health conditions such as gastrointestinal issues, migraines, fibromyalgia, chronic fatigue, joint/muscle pain and sinus issues. Rather than just treating the symptoms as is often the case in medicine, my aim is to partner with my clients to help them discover the root causes of their symptoms. Compassionately listening to my client’s story along with utilizing some of the most advanced functional diagnostic tests available, we can better detect root causes of illness. As a certified food sensitivity specialist, I utilize MRT (mediator release test) which takes the guess work out of pinpointing the exact foods and food chemicals which trigger systemic inflammation in the body. Based off this test, along with other functional labs, and a deep assessment of my patient’s health history, symptoms and goals, I am able to provide a highly customized nutrition/lifestyle protocol to support the overall health and wellness goals of my clients.


Let’s work together! I would love to help you get started on your own journey to optimal health!
