Making Root Cause Medicine

available wherever you are.

“Due to patient demand, we offer our care to those living anywhere in the U.S. Individuals from across the country asked for our help because they were unable to find it locally. There are very few clinics that have decades of experience in Functional Medicine and provide a team of doctors working together to identify the root cause of your exact health care issues.”

       -Dr. Vikki Petersen, Founder

Our team of doctors specialize in Internal Medicine, Functional Medicine, Physical Therapy & Chiropractic.

We are known for our incredible diagnostic skills and testing resources that allow us to pinpoint the exact root cause of your health concerns.

We know the body can heal itself; it simply requires identifying what is overwhelming or overburdening it. That is our expertise and it explains why our success rate is so high – 85%. You deserve exacting and personalized care. It’s the only care we offer here. Each program is tailored to and for you. Fortunately, we are able to cater to your treatment needs even if you live out of state or at a distance from our clinic.

How Does a Functional Medicine Program Work?

Cost is a common question and should be.
At Root Cause Medical Clinic programs are custom designed for each patient.

You have had your own personal journey in your life – your health, your genetics, your childhood are all unique to you. We therefore create a program just for YOU.

Programs can be 12 visits, 18 visits or more, although most programs are around 15 visits.
Each program lasts several months, with the frequency and total duration dependent upon your health condition.

The average cost of each program is $3,000 to $6,000. If that sounds like a lot, keep in mind a single cup of coffee at your favorite coffee shop will cost you about $2,000 per year.

A single drug prescription can run $38,000 per year! And that’s a drug with life threatening side effects.

Our programs are not repeated. If you follow what you’ve learned as regards your diet and lifestyle, maintaining your good health is relatively easy and perhaps requires a couple of visits every two years.

Is it worth a few thousand dollars to regain your health naturally? We think so, and our 85% success rate proves we know what we’re doing.

We are often able to provide remote care. Call us to find out if you qualify for exclusively remote treatment.

We’re often asked what exactly is done at Root Cause Medical Clinic. How do our programs work?

We are a team of doctors addressing not just internal medicine but structural medicine as well.
In other words we address your whole body. As a team of 6 doctors, we collaborate on the very best approach to help you regain your health. Our 85% success rate proves we know what we’re doing. Further, our belief in the human body’s ability to heal itself when given the correct help, speaks volumes. It results in a respect for the body, a willingness to listen and understand it, and provide it with the most natural solutions possible.

We have an 85% success rate.

What our patients have to say about us:

"I’m happy that I found Root Cause Medical Clinic and was able to get my life back really through a natural, root cause approach. I had tried all the different medications and pills that numerous doctors and specialists threw at me. They didn’t work for me. Nothing had solved the problem. Everything they offered was just a band-aid for what was really happening"


'When I started with Root Cause a year ago I was pre-diabetic, had hormone deficiencies and also digestive problems. For several years I’d been working with other doctors trying to handle these issues, but with no success. My daughter-in-law, along with another very good friend recommended I go to Root Cause Medical Clinic and work with Dr. Rick and Vikki Petersen and the medical doctor. I am so glad that I took their advice! Under the guidance of the doctor, I am no longer pre-diabetic (YAY!) and my hormones are now balanced. I sleep like a baby and feel full of energy."


"The services I’ve received here have changed my life. I had a stroke 6 months ago, and while I recovered very quickly, there was still something not right with me. I had a hard time sleeping and was having constant heart palpitations and daily anxiety attacks.

Through the nutrition assessment, I discovered that I had food sensitivities to corn, quinoa, teff, and amaranth that I hadn’t known about. Once I removed those, I took it a step further and removed all animal products. A wholefood plant-based diet was LIFE CHANGING!!"
