Dr. Nathan David Keiser

Dr. Keiser's approach to treating patients with complex neurological disorders is one of a kind. His ability to identify specific areas of dysfunction using a unique combination of diagnostic tests, leverage an individual's strengths to improve weaker neurologic processes, and use real-time biometric data to ensure he never overdoes treatment sets his work apart from all my prior neuro-rehab experiences. His holistic approach is well suited to improve and integrate vision, vestibular, musculoskeletal, and autonomic systems the way the brain and body intended, rather than addressing each with individual specialists as is done in a traditional medical setting. Beyond his brilliance and problem-solver attitude, Dr. Keiser is a compassionate, humble, and devoted clinician. From your intake call with Claire, to your post-treatment check-ins, you will be met with warmth, and a motivated team to help you get to the life you want to live.

I believe Dr. Nathan Keiser was able to find my root issues through a thorough evaluation. He was able to show me the proof of the issues and explain the path of healing forward. I went a while without knowing answers before Dr. Keiser. He started my healing journey in his office and helped me have the ability to continue treatment at home. He is very knowledgeable! I super appreciated him being able to answer so many questions to help me learn about my condition.

I’d been struggling for months and knew something was wrong, but every doctor I saw blew me off, one even laughed when I discussed my fall. After one visit with Dr. Keiser, I had an answer and a personalized plan for recovery. He and Claire demonstrated compassion and positive words of encouragement as I navigated the challenges of putting my life back together. Dr Keiser’s knowledge is abundant and he uses a functional individualized approach to correct a person’s deficits to improve their quality of life.

I was skeptical at first, but was amazed with the results. I had neuroborreliosis, which is a fancy medical term for when Lyme disease enters your CNS. Inflammation in my temporal lobes created difficulty with auditory processing (following basic TV), short term memory, along with speech and word retrieval. Dr Keiser continually demonstrates a strong command of his field, exercising a refreshingly rare balance of a bedside manner, insight and knowledge and a unique ability to memorize each individual and their case. Furthermore, he remains a curious student of functional neurology, constantly and continually learning for the betterment of his patients. He explains and articulates what is causing the vast symptomology one is experiencing and effectively conveys how to treat it. I do not know where I would be without him.

Have been to and referred difficult patients to Dr. Keiser! Simply the best. Thank you for all you do!

I fell on ice in 2016 and have struggled with post concussion syndrome ever since. I have seen just about every kind of care giver I could find, always just marginally getting better. I had more improvement with Intensives at another Functional Neurology Clinic, but I had lingering issues- particularly my inability to drive beyond 30 miles without exacerbating my symptoms. This impacted my life. Dr. Nathan Keiser was able to diagnose a vision issue last year that had eluded every other practitioner, and with such a simple test! I can now drive over 6 hours at a time which is a huge breakthrough. Chelsae is also a very nice town to stay in! I highly recommend Dr. Keiser- do not give up hope!

Ugh. Dr. Keiser. I can't say enough great things about my experience with Dr. Keiser. I am a little bit of a complex case and have seen him multiple times. I'm going on a year of working with him from damage to the nerves in my legs to damage in the brain. He gets to the root cause of your neurological issue and addresses it in a way that no other doctor would. Kind, patient and amazing bedside manner. He still supports me from afar in my recovery and I am so grateful for this and his expertise. His wife, Dr. Claire Keiser is amazing as well- addressing all your needs before, during and after your visit to Chelsea. They are a power team. Overall, I truly don't believe I would have had half the results I've had if I went anywhere else. Doctors at the hospital told me nothing was wrong with me even though I had been bedridden for months. Dr. Keiser truly is a gem and a brilliant practitioner..... and Chelsea Michigan is an adorable, sweet town that you will enjoy traveling to for care.

At first I was skeptical as I just knew my TBI would be the end for me. Dr K put all my skepticism in the garbage. I’m walking proof that this man knows his stuff. He is so down to earth and takes the time to explain everything ….in regular words. He doesn’t speak over you at at you he speaks WITH you. I have mad faith and respect in Dr.K. You will too!

I can honestly say, Dr. Keiser saved my life! I walked into his office feeling cautiously optimistic that he may just be able to do what many others had been unable to- give me hope. Dr. Keiser’s treatment regimens are structured and adaptable to one’s progress. The exercises are intense but if you commit 100% to following them, you WILL see change! Dr. Keiser’s knowledge of how the brain functions led me to a better understanding of my TBI and what realistic expectations I may be able to reach. The weeks I worked with this man have forever positively changed me life!! Dr. Keiser is a “brain wizard.” ????

Dr. Keiser is the GOAT. He is the only Dr that was able to help me get back on path after my major concussion (that led to Afib). His knowledge and confidence gives you hope that you will improve your health. I have been able to apply his wisdom to my life and continue making my health better. I highly suggest seeing Dr Keiser if you need help with your health.

There are no words to really describe Dr. Kaiser and what he is capable of accomplishing. I stumbled into his clinic as a last resort after I tried EVERYTHING. He is so kind, generous, compassionate, intelligent, and down to earth. His knowledge and ability to teach surpasses anyone else that I know. If you are struggling, reach out. I promise you won't regret it. If I could I would spend 365 days on his clinic. You are on good hands!

Doctor Keiser has been able to restore balancing issues and feeling in my hands and feet which hospital doctors said would never return. Dr. Keiser is one of the wisest and kindest doctors I’ve known in my recovery journey. His diagnostic attunement and abilities in neurology are outstanding. I also feel blessed to have worked with such an unbelievably highly skilled doctor. Thank you doctor Keiser.

Dr. Keiser is amazing! I highly recommend making an appointment. He has helped me get my life back. Before my sessions with Dr. Keiser I had debilitating hemiplegic migraines and numerous other issues. I can’t thank him enough!
