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.

It’s Official! Food IS NOT food
Well, we sort of knew that, given the genetically modified corn, soybeans, cotton, canola, sugar beets, and the list goes on1. In this case, however, I am referring to an NPR story2 on the new dietary habits of animals at the Melbourne Zoo. “ . . .the monkeys are no...
Healing is Being an Interpreter of the Body’s Symptoms
The human body speaks a “foreign” sensory language. It would be nice if it could speak English, and say, “That pasta you ate last night is fermenting a lot of fungus, and I’ve told you before about your auto-brewery problems, so take extra probiotics today, and eat very lightly, and please, no carbohydrates.” Instead of […]
