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.

Natural Remedies for Common Ailments
Many people are looking for healthier options to common problems that may be as as effective as pharmaceuticals but not have side effects, and may resolve the underlying cause of the health challenge. The following natural remedies are what I use in my naturopathic practice at National Integrated Health Associates (NIHA) with great success. While these are generally very safe in small dosages, as with any herbal or homeopathic or medication you should first consult your naturopathic physician before using these recommendations. While natural medicine’s efficacy lends itself to both the expertise of the doctor and the commitment of the patient to take care of themselves, many natural remedies are quite effective in time of acute need.
You Need This for a Healthy Mouth
In order for us to have a healthy mouth we need to have healthy saliva. Saliva helps us to chew, taste and swallow. It keeps our mouths moist, fights bacteria and helps to prevent bad breath, gum disease and decay. If your salivary glands are healthy, your body could make up to two to four pints of saliva per day. Most of your saliva is made during the day. At night our mouths tend to be more dry.
