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.

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!"

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 experienced miraculous results after visiting Dr. Rosenfeld.

"My back for no apparent reason was so painful.  I couldn't move.  After two days in bed a friend recommended I see Dr. Rosenfeld.  I could barely drive or sit when I came in.  This had happened several times in the past twenty years.   A medical doctor had given me muscle relaxers only.  They weren't all that helpful but over time and with restricting activities I got better.  I experienced miraculous results after visiting Dr. Rosenfeld.  I am able to do more than before in movement and strength with no pain, my whole outlook each day is more positive and I feel more energized."

Dr. Rosenfeld is a great teaching Doctor.

"I was in a car accident and had a back and neck injury.  In addition, I had pain in my hip and tingling in my cheeks.  A long time ago (before my accident) I had visited a physical therapist that hooked me up to electrical stimulation and put heat on me for weeks.  Over time I got better.  I found Dr. Rosenfeld through my PPO Blue Cross list of providers.  The first couple of weeks were learning new habits and each time and each visit I have learned more of what I can do to maintain the relief that Dr. Rosenfeld has brought me.  I am able to work without pain for days at a time and I know I can return to Dr. Rosenfeld's office and get support for continuing recovery.  I am still working on permanent neck pain relief but my lower back, hip and cheek tingling are gone!  Wonderful.  Dr. Rosenfeld helps me and motivates me to keep coming in! Her office staff is completely supportive and knowledgeable too.  Dr. Rosenfeld is a great teaching Doctor."

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!"

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."

It was amazing.

"I first came to Dr. Iris's office in April of 2004.  At the time, I was in bad shape.  I had recently pulled a neck muscle, was extremely fatigued and could not concentrate on my course work.  I suffered from many food allergies and an extreme sensitivity to gluten.  Within 3 visits my neck pain was gone.  Dr. Iris had recommended certain supplements which helped immensely with my fatigue and concentration.  Within a year of starting the allergy treatments, my food allergies vanished, including my gluten problem (which was deemed impossible by other doctors and allergists I have seen) along with a dust allergy.  It was amazing."

- Amy

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."


Dr. Rosenfeld has given me lasting relief from pain

"In 1982 I was catapulted from a motorcycle causing whiplash, neck and low back injuries.  Many years of an untreated condition and compression created much pain, discomfort and subluxation.  After seeing another chiropractor for 15 years it was time for a change.  During those 15 years I had many visits and physical therapy that gave me temporary pain relief and muscle toning and strenuously.  Temporary relief.  I was referred to Dr. Rosenfeld by Barbara Anderson who is a Rolfing therapist.  Dr. Rosenfeld has given me lasting relief from pain and the ability to maintain a longer adjustment much and I have much gratitude and appreciation!"

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."
