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.

President Donald Trump[1] has just proclaimed September 2017 as the National Alcohol and Drug Addiction Recovery Month. One can’t fault any concerned American for bemoaning our #1 national epidemic that continues to escalate with no solution in sight. In true Trumpesque form, the issue is being met head on and brazenly confronted, a welcomed call to action. Deaths from drug abuse kill more Americans by far than any other disorder, with tobacco alone killing nearly a half million Americans per year and underlying much of the death and disability of the classical #1 and #2 killers, heart disease and cancer. Deaths from opioid abuse alone, heavily fueled by the prescription pad, now tally more than the deaths from auto accidents and gunshot wounds combined.
