About this clinic

Great Lakes Functional Neurology, a functional-medicine clinic in Grand Rapids, specializes in neurological rehabilitation for brain injury, concussion, dizziness, and dysautonomia. The practice combines chiropractic care with functional-medicine assessment and offers hyperbaric oxygen therapy and laser therapy as adjuncts to its neurological protocols. Hormone replacement therapy is available for patients whose treatment plans indicate hormonal support as part of recovery. Treatment is individualized following a comprehensive intake, and the clinic emphasizes evidence-based sequencing of modalities to support neurological healing and autonomic function rather than symptom management alone.

Great Lakes Functional Neurology truly changed my recovery journey. I was diagnosed with a pinched nerve and even after physical therapy elsewhere, I still couldn’t lift my right arm without pain. After seeing Dr. Chris Sass, he recommended electric stimulation therapy — and it worked like magic. The difference was incredible. What really sets this clinic apart is that you work directly with the doctor. Dr. Chris personally handles your care — no being passed off to staff. That level of attention and expertise makes all the difference. Highly recommend.

I found Great Lakes Functional Neurology after the top POTS specialist's NP gave up on my case. After being in the traditional medicine system for so long, and even seeing some natural doctors on my journey, I kept my expectations low. But after just the first week of treatment at Great Lakes (after 20 years of suffering), I started feeling a big improvement. I was even able to go on short walks outside of my AirBnb. Once I returned to my home city after two weeks in treatment, I started the home exercises and have been getting better each and every day. After two months of home exercises, I was able to go on a day trip to the outlet malls for the first time in a longgg time last week + actually enjoy it with minimal symptoms. Highly recommend! It's worth every penny, and there is no better investment than your health.

I really enjoyed working with Dr Brian Sass! His treatments were very effective at helping me regain my balance amongst other things. He and his brother Chris are dedicated to helping heal people. Their facility is spotlessly clean, safe, and comfortable. Their approach, like their equipment, is cutting edge and very effective! Plan on seeing and feeling results right away. These guys set a high bar and achieve what other practitioners only dream of! 10 out of 10! Highly recommend!
