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.

Headaches and Sleep Apnea
Do you ever wake up with a headache, or get one by the end of the day? Are they associated with neck pain or do you have a separate neck pain? A new study from the University of Kansas Medical Center has shown that these symptoms are strongly associate with sleep apnea. This is a new association. Non supine sleep provoked by sleep disordered breathing (as with sleep apnea) may play a previously unrecognized role in headache and cervical radiculopathy, or neck problems of the upper spine.
