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.

Replace Those Missing Teeth with Ceramic Dental Implants
Your teeth serve many functions. Obviously they are critical for chewing and esthetics but more importantly if teeth are not replaced especially posterior or back teeth, that empty space will allow neighboring teeth to drift into the space formerly occupied by the extracted tooth. Without replacing that missing tooth the neighboring teeth above and to the sides will move into that space altering the way your teeth come together. That altered bite changes jaw alignment, blood flow to and from the brain as well as alters the nervous system function throughout the head and neck. Bite changes will eventually disrupt the TMJ or jaw joint.
Not Feeling Better? Try Autonomic Response Testing, ART Muscle Testing
Fatigue and pain are two complaints that every physician hears at least once a day and a growing number of people in the USA are experiencing at least once a day. They are the two most prevalent symptoms that patients describe when they become desperate for help. Every day I hear the phrase “I have been to fifteen different doctors and no one can tell me why I’m sooo tired or at least give me something to fix it”. So what is keeping these doctors from finding the answer?
