Measuring is Knowing

  • Knowing and optimizing your brain function is vital to protecting the quality of your life.
  • People are living longer but we’ve neglected the most important organ that commands our entire quality of life, the brain.
  • The problem with most brain health tests today is the failure to provide information that helps you take control over the most important factors under your direct control.
  • The BrainSpan® test uniquely combines a performance test with a nutritional bloodspot analysis that is easy to understand, objective, and actionable.
  • It is backed by over 100 peer-reviewed scientific publications in each of the two parts that make up the testing experience.

Brain health and prevention of cognitive decline is heavily influenced by decisions you make every day.  Find out if a BrainSpan® test might be right for you!

Free Brain Grade Survey

Cognitive decline is inevitable as we age. But we can take simple, straightforward steps in our day-to-day life that can drastically slow or prevent the decline so that any noticeable impairment is delayed for decades or even prevented altogether.

Click on the link below for your Free Assessment from BrainSpan® that will provide both you and me with your “Brain Grade” based on a 5–10-minute survey of questions about your diet and lifestyle. If your score is less than 90, you are at risk of experiencing impairment far earlier than optimal and that makes you an ideal candidate to take a more specific test available at my office.

If your Brain Grade does identify you as a good candidate, we will reach out to you to get you a test kit. This kit includes a small finger stick for specific blood metrics and a cognitive function test on a computer you can do at home. We will discuss specific recommendations for helping build your resilience to decline and improve your overall functional longevity as you age.

To start your free Brain Grade survey, simply follow the instructions below:

  1. Go to https://www.brainspan.com/braingrade
  2. Be sure to enter my name as the referring practitioner , Iris Rosenfeld, DC and my email which is [email protected]
  3. Complete the survey and then call our office or we will call you if your score is less than 90 for the BrainSpan® NeuroHealth Assessment Test Kit.

Thank you for taking this critical step in protecting your most important health asset, your brain.

We Love Our Clients!

Thank you for taking the time to read these reviews.

I would give 10 stars if I could.

"I would give 10 stars if I could.  Dr. Rosenfeld is the consummate professional!

If you want to get the best chiropractic care available look no further. I must receive impeccable care/service for me to write a review. Dr. Rosenfeld will increase your quality of life and reduce your pain. This is all done in a professional manner and setting. The staff is just as professional as Dr. Rosenfeld which is extremely important to me!  I have been to numerous Chiropractors and very rarely will I return for a second visit. My search took over 6 months to find the right Dr and care. And the office hours should accommodate anyone's schedule. 

Thank you Dr. Rosenfeld. I'm so excited to have found you!"

My back is a lot better

"I have suffered back strain on and off since December 2006.  Picking up something or my weight caused it and I could not go to work so it was pretty severe.  I saw another chiropractor on and off and got some good results but it didn't last.  I found Dr. Rosenfeld on the internet and through my husband's insurance.  My back is a lot better and now we are working on neck pain and stress in my upper shoulders from work and day to day activities.  Massage has helped as well."

Dr. Iris is a wonderful and caring doctor.

"Dr. Iris is a wonderful and caring doctor. I have been fortunate enough to be her patient since 2012, when my large toddler was causing havoc on my back. She was easily able to get me out of pain and back to functioning order and has been doing so ever since.

She has an amazing intuition when it comes to the body. She is able to find the little spots that are out of alignment, even if I'm not able to locate them myself, and put them back where they belong.

She is completely committed to her patient's well being and will do everything in her power to make you well, body and mind!"

My neck is feeling so much better

"I had neck pain that I had suffered from since a car accident in June of 2005.  I suffered with this pain everyday - sometimes mildly and sometimes more severely.  Also, my adrenal glands were shot and I was feeling a lot of stress.  I had been seeing another chiropractor for about a year with little results.  My pain never really went away despite facet blocks, trigger point injections and physical therapy.  My mother told me about Dr. Rosenfeld and I made an appointment.  My neck is feeling so much better.  My flare-ups are few and when they do occur Dr. Rosenfeld resolves them quickly.  The DSF supplement has helped me tremendously.  I no longer feel frazzled or out of sorts.  Thank you!!!"

I have had issues with headaches and back pain for many years.

"I have had issues with headaches and back pain for many years.  In addition, I have had problems with general pain issues.  I had been treated by two other chiropractors, a physical therapist and a medical doctor.  I would get a bit better but then improvement stopped.  I had heard of Dr. Rosenfeld so I decided to make an appointment.  I have to honestly say that I have been feeling much better in a consistent manner.  The headaches are now rare and my body just feels better!"

Since seeing Dr. Rosenfeld, I have had progressive improvement

"I first came into the office in January 2008. I had a chronic issue with burning tightness in the right hip, extending to the middle back. It began about 10 years ago. I believe it was progressively getting worse but started with having a more sedentary job. It was not debilitating, but was annoying most of the time. I had been to my family doctor, an orthopedist, and another chiropractor. With the other chiropractor I had moderate results. The MDs had little to offer and no idea how to help. I found this office via a web search on the internet. Since seeing Dr. Rosenfeld, I have had progressive improvement, but the supplemental therapies have been both helpful and entertaining."

I am being treated by Dr. Rosenfeld for pain relief.

"I am a law enforcement officer.  I had middle back pain like a pinch under the left shoulder blade area.  This limited me from working out and running.  I was very conscious at work with regard to my profession.  I had heard from a friend that chiropractors thoroughly studied the spine, concentrated on one discipline as opposed to western medicine.  I am being treated by Dr. Rosenfeld for pain relief.  Because of the long hours of sitting in a radio car or long hours standing and the approximately fifty pounds of gear I wear on a daily basis, I don't have the small aches and pains I used to have. I have talked to several of my co-workers who complain of back pain and told them to consult a chiropractor.  I have also told them about some of the other services Dr. Rosenfeld provides."

Previously I have seen a GI and an Allergist, with no help.

"I first came into the office on April 2007. I had food and environmental allergies. The allergies were moderate and caused mental fog, fatigue, stomach cramps and IBS. Previously I have seen a GI and an allergist, with no help. Because of the treatments I received here, I am 85% recovered. Most of the foods which caused troubles do not currently cause any symptoms."

- Mandar

Her patients come first there is no question about that.

"I have known Dr. Iris for over 15 years & in all that time she has never wavered from being not only a professional in her field, but treating you like a friend. She has always taken good care of me & made time to see me when I've needed her care. She is always on a quest to learn more & educate her patients so they can lead  healthy lives. Her patients come first there is no question about that."


I have actually been pain free more days than not and have been sleeping better.

"I had Sciatica and lower back problems with immense pain.  I could not sit, stand or lay down without absolute pain.  It had been ongoing for the past ten years and I think an old fall down the stairs started it.  Basically I would only go to a doctor at the urgent care when it was severe enough.  They gave me muscle relaxers and Vicodin.  They helped but not for the long term.  I was referred to Dr. Rosenfeld by Hilary Arnatt.  The results have been amazing!  I have actually been pain free more days than not and have been sleeping better.  Thank you!"
