About our Clinic 

Heath is not the absence of disease. 

Our society is trained to think that if you have no symptoms you are healthy. Cancer, arthritis, diabetes, heart disease, autoimmune disorders all do not happen overnight.  The problems that lead up to these conditions took time. Many of them have tell-tale signs, if you know what to look for. Using the tools of the laboratory such as genetic testing, heavy metal testing, organic acid testing, urinalysis, blood tests, comprehensive stool analysis neurotransmitter analysis and hormone testing, one can get a complete analysis of how YOUR body chemistry is working.

This office has had great success with digestive, endocrine, allergy, liver and many other INTERNAL problems. If a drug is necessary, it is necessary. If so, why not look to see what is being depleted by the drug and support the body chemistry. But, if you could take a NATURAL substance to eliminate your problem, would that not make sense?

Out goal is to help you to understand health problems and to find individualized treatments that address the cause of your health problems, and not merely treat symptoms. Many things in the life rob us of great health. Poor diet, unhealthy lifestyles, genetics, plus many other factors lead to an unhealthy state.

The question Dr. Hult tries to determine is WHY. Why do you have rheumatoid arthritis, why do you have adult onset diabetes, why do you have lupus, why do you have high blood pressure, why do you have heart disease. All of these conditions have and answer.  You need to know how to ask the right questions.
