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.

Why Do We Really Love the Holidays?
What’s the real reason that we love the holidays like Christmas and Hanukkah so much? Why do we love holidays and holy days in general so much? How do we keep that sense of peace and joy in everyday life? What does truly make us happy in a lasting sense in life? Often times in life, especially when we are children, we think that we love the holidays because we get to receive gifts and eat good food. Yet, even as children, the winter holidays evoke so much hope and love and joy and positive expectation about life. I would suggest that the real reason we love the holidays is that we do experience (so many of us do, anyways) at least hope, usually along with a good dose of love and peace, and maybe even some joy.
Health Tips for the Fall Season from Chinese Medicine
Fall brings harvest time, the beauty of the changing leaves, and less daylight. In Chinese medicine, fall is associated with the element of metal and the lungs. It is a time to slow down, go to bed early, regroup and begin to move and think inward in preparation for winter.
With the change to cooler weather comes your body’s attempt to cope and wild fluctuations in temperature which are giant stressors on the system, bringing on colds and flu. Is there a way to prevent these seasonal health missteps? Of course!
