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!

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 driris@driris.com
  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.

Thank you for taking the time to read these reviews.

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!"

I have experienced relief, blessed relief!

"I have neck pain.  I recall various incidents that triggered it… reaching into a desk drawer, sleeping on a new pillow, etc.  I have seen other chiropractors and some helped and others didn't.  My mom introduced me to Dr. Rosenfeld and I have experienced relief, blessed relief!"

Overall my results have improved tremendously with spinal decompression therapy

"I have had been having spinal decompression therapy for the last month. I have had excellent results. I was having sciatica and neuropathy; after the first treatment the neuropathy was so much less!   Dr Iris and the office staff are very professional, efficient and caring. Overall my results have improved tremendously with spinal decompression therapy. I would recommend Dr Rosenfeld to all patients with back problems, she listens and will work with you to improve your life."

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!"

I chose Dr. Rosenfeld to help me continue on the road to good health.

"I had just moved to this area.  I had been seeing another chiropractor on a regular basis to help with knee problems and other aches and pains that cropped up.  After I moved I chose Dr. Rosenfeld to help me continue on the road to good health.  I had also received physical therapy for my knee.  Physical therapy worked well but only focused on my knee.  Chiropractic treats my whole body.  Other areas of my body need adjusting to help keep my knee functioning well.  I found Dr. Rosenfeld through the yellow pages.  I am now in my 5th year of chiropractic care and I wonder how I got along without it in the past.  My knee is doing well and I am continuing to run."

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."


After seeing Dr. Rosenfeld, I have no pain in my neck and great mobility.

"I first came to the office in 07/07. I came to the office because of pain in my neck and shoulders that I have had on and off for years. I also had very limited mobility. In the past I have been treated by other chiropractors with only temporary relief. We changed insurance plans and after much research I called Dr. Rosenfeld. After seeing Dr. Rosenfeld, I have no pain in my neck and great mobility. There is still some aching in the shoulder, but the mobility is much improved."

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."

I love coming into this office.

"I had tremendous pain in my lower back and neck.  I could barely walk or even function normally before I came to see Dr. Rosenfeld.  I had this condition on and off for years, but never to this degree that caused me to finally seek professional help.  I was given Vicodin, Soma and Naproxin by a regular family physician.  The medication only temporarily took away my pain.  I never had any other treatment other than a physician who prescribed me these medications.  One of my husband's friends spoke very highly of Dr. Rosenfeld so I called her.  I have gotten great results!!! I am finally recovering from my back/neck injury.  Dr. Rosenfeld and her entire staff have been extremely caring and helpful.  I love coming into this office."
