We deeply appreciate our patients' reviews and comments, because we want to be as personally and organizationally healthy in mind, body and spirit as possible too!  We know that each of our healers is unique and that finding the best match between patient and practitioner improves healing.  We present these reviews, with patient permission, as patients have written them, whether positive or critical.  We know that we can always improve and believe that these reviews are helping us to do that.




The atmosphere in the Lab is peaceful, relaxing, and healing. All the Lab staff are caring, compassionate, patient and very attentive to my needs.

Dr. Kannankeril

After 14 years of pain, finally I have a cause! Dr. Kannankeril  tested for things other doctors would not.

Laurie DeRosa, Dental

Everything is more than satisfactory. Laurie DeRosa is the best dental technician I've ever encountered, and always a pleasure to talk to.

NIHA and Dr. Kannankeril

NIHA is the best doctor's office I have ever been to. Dr. Kannankeril is very thorough, kind and understanding. I love coming here, and visits almost seem like a calming therapy session. I have recommended the office to many friends and two are now patients too.

This place is a godsend.


This place is peaceful, warm, clean, accessible and more. Many of the airborne allergens have been removed.

Dr. Coy Roskosky

Awesome appointment with Dr. Coy- We got my neck to crack on the stiff/tight side for the first time in 20 years! He is the most amazing chiropractor!


I love the personal attention and time spent answering my questions about thermography, explaining everything, and addressing all issues. Unlike any other medical experience.

Dr. Kannankeril

Dr. Kannankeril is the best doctor I have ever had. A most caring person!

Dr. Gant

I am so happy that it is possible to perform such specific and thorough testing and to be able to work with an encouraging and brilliant doctor as Dr. Gant.

Dr. Frandsen

Dr. Frandsen is very thorough and on-site lab are the most satisfactory parts. Also she's a compassionate doctor with knowledge of my issues that are not even validated by conventional doctors.

Dr. McClure

Dr. McClure and entire dental staff: Thank you so much for your kindness, patience and courtesy. I am petrified of dental offices and I really appreciate all that you did for me. The care received from NIHA is irreplaceable in Washington DC. K.C.

Dr. McClure, the reason I am still alive

Dr. McClure and staff are the reason I am still alive and I am eternally grateful.

All the best to NIHA's continued success.

Dr. Kannankeril never in my 36 years

My visit was excellent! Dr. Kannankeril's approach to my health concerns made me feel confident that I am in good hands. In my 36 years, I have never had a healthcare professional take so much time to talk to me. R.S.F.
