Discover Functional Medicine

Looking for a Functional Medicine doctor? We are here for you if you’re ready to truly get to the root cause underlying your health problems.

We live in a country that doesn’t appreciate how amazing the human body is. Why do we say that? Most symptoms are treated with a drug – a drug that masks the symptom temporarily WHILE creating dangerous side effects.

Certified Functional Medicine Practitioners

Our team of Functional Medicine doctors are trained in a methodology that respects your body AND its ability to heal itself. If your body is able to heal itself, why do you need us? Good question! When the body is not overstressed and overtaxed with problems, it CAN and DOES heal itself. When you get a minor cut do you need to DO something about it? In most cases you don’t. The body’s immune system simply heals the cut. But if you have diabetes or poor circulation, even a minor cut can take a long time to heal. The difference is the body that doesn’t heal the cut readily is not as healthy or resilient as the one who does so effortlessly. The latter is a healthy body.

The example of the cut was just that, an example that’s easy to understand. If the symptom is fatigue, headaches, digestive problems, joint pain or hormonal imbalance, the same holds true. As soon as the body gives you a symptom it is “telling” you that it is overwhelmed and needs help. If it could have handled the underlying issue on its own, it would have done so, and would have had no need to give you the symptom in the first place.

The dramatic increase in autoimmune disease in our country is another good example of where, in our opinion, the current medical model is failing us. In autoimmune diseases, the body’s immune system is attacking the body instead of what it is designed to fight, a true hostile invader such as a bacteria, virus or cancer cell.

When someone is diagnosed with one of over a hundred different autoimmune diseases, they are told there is no cure and they must suppress their immune system because it is “out of control”. While we agree the immune system is operating incorrectly, suppressing its ability to function is not the answer. Such drugs (immunosuppressive drugs) come at a high risk of death from infection. With the immune system put out of commission, you can get an infection and have no ability to fight back. The side effects are truly frightening.

A Patient Shared This:

The quality of my life (both physical and emotional) has benefited dramatically. I’ve had Fibromyalgia for 8 years. When I came to Root Cause Medlical Clinic 6 months ago I had experienced fatigue, muscle pain, migraines, insomnia and a general feeling of ill health. I was taking drugs for pain and drugs for sleep.

 Since beginning the functional medicine program I’ve had great success in either reducing or eliminating most of the symptoms’ severity. 

I began a modified diet after an adrenal test showed a change in diet would probably help some of the insomnia and muscle fatigue.

I began taking supplements which have helped stabilize my energy level.
I also began exercising regularly which contributes to the overall general well being I have continued to experience. 

I am grateful I was led to the care offered by the doctors at Root Cause Medical Clinic. The quality of my life (both physical and emotional) has benefited dramatically. This is my year to be well. And the success is due to the partnership I have with all the entire here.  — T.P.

I have been suffering for many years with illness, having been diagnosed with autoimmune diseases such as Lupus, Hypothyroidism, Asthma, and Osteoporosis. For the last year, my health had been deteriorating at an alarming rate. Thank God I found Root Cause Medical Clinic!

The doctors there are thorough and are concerned with treating the body as a whole rather than trying to treat symptoms, and the staff is very pleasant and helpful. Through the functional medicine program, I now have an understanding of what the probable root cause for my disease is, and can adjust my lifestyle accordingly. Dr. Rick Petersen does his follow up visits with me and has never been late for one of our appointments. He answers all my questions completely. Since visiting the clinic for the first time a month ago, I am showing marked improvement, and I consider Root Cause Medical Clinic to be a true lifesaver!  — Anonymous


What is the Functional Medicine approach? We get to the root cause of WHY the immune system is confused. Your immune system wouldn’t attack your own body if it had accurately identified it as you. When the immune system attacks various organs in the body it is because there is a confusion occurring; the immune system has confused self for a foe. The solution isn’t to turn the immune system off, but rather to identify the source of the confusion.

This isn’t just our opinion, much research exists to support this hypothesis and the fact it works with patients is the best acknowledgement.

Our functional medicine department sees success with treating autoimmune disease spanning from improvement of symptoms, to complete reversal of the disease. It is exciting for many reasons, not the least of which is knowing we are preventing further autoimmune diseases from developing through handling the reason or root cause why the disease began. Statistics reveal once a person has one autoimmune disease they are five times more likely to develop additional autoimmune diseases. By getting to the root cause of the problem, this tendency can be halted.

If you or anyone you care about suffers from an autoimmune disease, please forward this information to them. There is hope for improvement and potentially reversal.

And that in a nutshell is how we practice Functional Medicine. We are a team of doctors dedicated to getting to the true underlying root cause of why your body is giving you particular symptoms, and correcting the problem completely at the root level. Once the body is less burdened by whatever the cause or causes were, it can revert back to its natural tendency to heal itself.

We use standard and specialized laboratory tests, decades of diagnostic and treatment experience, and then design a program tailored to you and your needs.

It’s pretty darn cool actually and it’s something we never tire of seeing – a body that is restored to health and functioning optimally.
