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.

Genetic Testing – A New Way to Influence How Kids Turn Out?
A famous best-seller, The Nurture Assumption: Why Children Turn Out the Way They Do, by psychologist Judith Rich Harris, has been circulating for 20 years. Based on amassed studies, parental influences on children matter a lot less than peer group influences, and they both matter less than genetic factors. Parents are advised to not blame themselves if their children don’t become Rhodes scholars, because controlling peer group influences is difficult and controlling genetic expression is impossible. Until the last few years, parents were expected to do the best they can to control the friends that their children hang out with, and hope that their children’s genes will line up well enough to someday produce a productive, happy member of society.
