What Patients Say
Great office, best doctors. Dr Kalva is amazing to work with. Appreciate everyone here in the office, so helpful and kind.
Absolutely fabulous place. Best doctors ever.

I have been seeing Dr. Kannankeril for a few years and she is actively helping to get my body balanced and healthy. She listens, is knowledgeable, up to date with new treatments and excellent in her field. I always feel confident in her care that she is supporting me to great health in a personal way.
Dr. Kalva is an EXTRAORDINARY GEM of a doctor. HE IS ONE OF A KIND. He’s compassionate, warm, and highly skilled in functional medicine. He has great knowledge on thyroid issues and progressive treatment. He’s a wonderful communicator with teens and parents. We have been so blessed to find him. His care has been transformative for our family.
Dr. Coy Roskosky is the best Chiropractor I’ve ever been to! I even trusted him working on my children. My son played football and Dr. Coy help tremendously!
This is an excellent dentist office. After moving to the area, I struggled to find a great dentist. Most dentists in the area were still okay with mercury based fillings and routinely told me I had cavities when I suspected that was not true. NIHA provided a healthy experience and in my opinion are much more trustworthy.

What to Consider Before Taking New Prescriptions
In my over 30 years of practice as a holistic doctor, I have seen both types of patients. Those who arrive to my office with bags full of prescribed medications, and those who arrive with a suitcase full of “natural supplements.” (I’ve even seen fellow doctors do this.) What is wrong with this picture? Sometimes well intentioned doctors prescribe their patients a medication without reviewing what she or he has already been prescribed by another doctor, or sometimes patients neglect to mention a medication or supplement. When that happens, the new prescribed medication may dangerously interact with another the patient has already taken. Hospitalizations due to untoward effects of correctly prescribed medications range from 1.5 to 2.7 million cases per year. The death rate from the consumption of prescribed medications in the USA is estimated to be five times that of the rate for opioid abuse.
The Epigenetic Language of Food
When you eat a vegetable or animal, your body is listening to the epigenetic messages of its life, which are shaped by where it was raised and how it lived. Your body uses this information for its own health. This is one of the many reasons why the food you eat is so...
