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.

She and her staff go out of their way to try to fit you in for an appointment even if they are very busy

"Dr. Iris has been treating several members of my family for over a year now and we highly recommend her. I have been having chronic neck and back pain for several years and feel so much better after every adjustment. I also appreciate that Dr. Iris will recommend and provide vitamins or natural treatments for other health issues. She and her staff go out of their way to try to fit you in for an appointment even if they are very busy. She is very patient-oriented and is a fun and caring person to be around."

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."

I've never quite felt that before any health practitioner that I can remember

"Just want say thank you for the extraordinary commitment I feel from you to my getting better. I've never quite felt that before any health practitioner that I can remember."

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."

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!!!"

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."

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."

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."

- Mike

I was really impressed with the advanced equipment and techniques

"In April of 2008 I was struck by another car while driving and felt my neck snap and muscles in my upper body pull and tear. When I woke up the next day I had a migraine and was so stiff I could not walk. Dr. Iris saw me immediately and began working on me. I was really impressed with the advanced equipment and techniques she uses on accident victims. She eliminated my headache in the first visit and got me walking without pain quickly. I would never see or recommend another chiropractor as long as Dr. Iris is still practicing. She is such a wonderful person and talented professional."

- B. Davis

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."
