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.

Snowzilla Hits the D.C. Area, Thousands of Low Back Pain Casualties
After a big storm everybody has to go out into the cold and do hard labor. Shovelful after shovelful of wet, heavy snow is thrown onto a big pile so we can get to our cars, get the kids to school or even just open the front door. Unfortunately, shoveling snow is not a normal movement for us and can result in injuries we should not ignore, but many of us do. As soon as the pain hits, we start to get those loving reminders from our spouses to go have it looked at, but most of the time it falls on deaf ears. Some ibuprofen, Tylenol, heat and rest is what most people do. Then a week later you may be feeling OK. If it doesn’t go away most people continue to tolerate it until it resolves on its own or turns into something worse, and that can be a mistake.
