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.

Cut the Carbs and Lose the Weight
Have you been enjoying the hustle and bustle, the parties and leisure time spent eating and drinking with family and friends this holiday season? Are you ready to start the new year with healthy habits as your main focus? Many people tell me that the extra weight they carry around is their main concern – they want to look better and feel better. As a nurse and a health coach I understand that what’s at stake isn’t just how our reflection looks in the mirror, it’s how our future health will be 5 or 10 years down the line. The connection between the foods we eat and the health we get to enjoy is very real. Every time that we eat or drink something it affects our internal biology for better or for worse. During the holidays we get our fill of sweets, Xmas cookies, cakes, breads, chocolates, alcohol, cheese, crackers, candies, you name it!
