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.

Mindfulness Practice has been studied and found to be a useful and therapeutic adjunct in weight loss.[1] As a functional medicine physician, one thing that mindfulness can do that I have found to be clinically very helpful is to direct it at eating itself. A lot of people eat by the “chomp and swallow” technique which causes indigestion and gut dysbiosis.
Understanding the Human Microbiome: Mini Ecosystems in the Body
The microbiome refers to the full set of micro-organisms that inhabit a given site, most often (when discussing humans) the gut, but one might study the skin, oral, nasal/ lung or vaginal microbiomes. Each area has its own cluster of bacteria, or microbiota. Gut microbes make up the largest population within the human microbiome. When studying the microbiome, often the genetics of the microorganisms that live on us and in us, are the focus.
