I have been learning from and studying with Dr Chambers since 2014. He is an excellent clinician and a compassionate doctor. He has extremely high standards for himself and the type of diagnostic and therapy equipment he invests in to serve his patients. We have co-treated some severe autonomic dysregulation, brain injury, and neuropathy cases and have had some solid success. I am honored to be his colleague and so glad that I am able to tap into his knowledge and expertise to improve my personal health and to help me when I run into some difficult clinical cases.

Dr Chambers is a doctor you can talk to and know he is listening to what you are saying, He will explain treatment and diagnosis in away you will understand . He takes the whole person into account not just one ache or pain and then explains how they all go together to be able to function properly So grateful to my friend for sharing him with me.

Dr. Chambers is amazing and extremely knowledgeable, took him 20 minutes to diagnose what my doctor still hadn't after 2 years. Cassie the massage therapist is incredible! Friendliest office staff you'll ever find. Heather, Melissa, and every single person who works there is wonderful!

Dr Chambers literally saved my life. I have MS and I was experiencing non-stop symptoms. He found my celiacs disease and other food allergies. 18 months ago I was in the hospital and my organs were shutting down. Now I’m back at work and exercising. He is a little more expensive but how much would you pay to feel better?

🌞👍🌞👍Dr Chambers and his staff are awesome!! He is helping me with health issues that other doctors were unable to figure out. You may have to modify your diet either for a short time to heal your gut and get rid of inflammation or you may have to change your diet for the long run if you have autoimmune disease but at least you will have answers and a chance to change your life for the better. He is great at explaining all the hard stuff and reading blood tests, I found he noticed many things the other Drs missed. I am currently waiting for my Autoimmune test panels so we can get answers as to what foods I should avoid and although it can be hard to give up foods, it is much better than being sick and miserable. Thanks Doc!!

Update on my previous review. Dr. Chambers is very knowledgeable on Hashimoto’s and is guiding me to a healthy lifestyle to be able to move forward without all of the symptoms I’ve been suffering with. I’m 3 months in and my body is making good changes, things we didn’t think would happen for a few more months.

Dr Jon Chambers is the most rounded educated Chiropractor of his type. He doesn’t guess about what might be happening with me, after repeatedly getting an adjustment for a particular area. Blood work ups are ordered, he then proceeds from there. His knowledge of holistic supplements along with what they can accomplish is very good. I’ve no doubts that I could’ve been hospitalized if he hadn’t ordered blood tests when he did. He’s even helped me to identify what foods I’m allergic to. No need to hestitate to make an appointment with him. He has a great staff as well, all working towards getting patients on the road to recovery from the standpoint of the whole body.

Dr Chambers has changed my life! I am no longer on all of the harmful medications i was taking, due to his guidance for dietary change! He is very knowledgeable when it comes to autoimmune diseases and reading blood work!! I love that he gets blood work and uses that to guide your treatment. I have recommended to many of my friends with autoimmune problems to go see Dr. Chambers.

I've moved to GP from Portland just a year ago. In Portland I have seen every kind of Dr imaginable, for 20 plus years I have suffered with severe chronic pain in my neck and down my arms, now get this, within ONE week of doing what Dr Jon told me to do 3/4 of my pain was GONE, most days I have ZERO pain, once in a while I have little flair ups but we are working together to eliminate those. Dr Jon is my miracle Doctor, If you are in pain, give him a try, I promise you, if you do what he says, you will find relief .

Dr. Chambers is amazing - so knowledgeable. You can really tell that he truly loves what he does. I've been seeing him for just 1 month and so many of my issues have cleared up... more to go, but I'm so grateful that I'm actually feeling so much better. Dr. Chambers doesn't just want to make you well, he wants you to actually be healthy. As an added bonus, he has once a month classes which are packed full of valuable information and best of they are FREE!

Dr. Chambers is a rare doctor among the many doctors and specialists we have these days. He aims to help the body heal itself. He does not treat the symptoms, but the person as a whole. I was really impressed with his ability to identify the underlying issues to my debilitating chronic pain so quickly. ALL the other doctors and specialists I saw over the years and the multitudes of tests I had done, never helped the doctors figure out what was wrong with me or how to help me. Dr. Chambers seemed to know what was wrong with me and how to help me. My health continues to improve everyday. Dr. Chambers has profoundly changed my life and my perspective on health!

This would be the second time in my life that i have had a long term ailment which no other office or care provider could put their finger on or much less provide me with a solution. Can't thank the Neuro Clinic and Dr. Chambers enough for their dedication to their patients' well being. I am happy to be a patient here for life.

Dr. Chambers was recommended to me as a chiropractor by a friend and co-worker. After completing a thorough questionnaire and examination, Dr. Chambers was quickly able to help my back pain as well as other muscle pain that I thought I would always have to endure. I expected to receive help with some back pain and numbness, however, I am thankful for the unexpected help he has given me with my overall health and mental concentration.

I can't imagine where I would be if I didn't make the changes I did and take control of my health. I have made changes for my family as well and can see a considerable difference with dietary changes alone. Dr. Chambers and his staff are fantastic. I recommend them to everyone!
