Posted on Doreen and Keyvis Summers-WashingtonTrustindex verifies that the original source of the review is Google. I truly believe that every person dealing with stress, depression, anxiety, accidents aside from getting physical therapy should do mental therapy. This is state of the art neurology therapy. Not only can you speak to a therapist, they have state of the art equipment to help you recover mentally and physically. From neuro feedback to oxygen chambers to speaking to one of the most smartest persons I’ve encountered, Dr. Em K. The entire staff is so knowledgeable and helpful. Since my appointments, I have surely changed because of this therapy. I remember getting irritated in traffic- now I’m listening to classical music and letting people be them. Total 180. I applaud and appreciate each and every one of you, from Michelle to Connor to Julio to Xaeden to GiGi.. thank you for this life change ❤️❤️❤️❤️❤️❤️❤️❤️❤️Posted on Holly PeacockTrustindex verifies that the original source of the review is Google. Very helpful and friendly staff all around 👍💯Posted on Robert CurtisTrustindex verifies that the original source of the review is Google. Dr Gleis is brilliant. Melissa is awesome. Good folks who know what they are doingPosted on Mike HydeTrustindex verifies that the original source of the review is Google. I can't thank Genesis enough. I was in a severe car accident and was struck in the head and back. I couldn't put a sentence together because my brain wasn't working ,and in alot of back pain. I am on my 8th session and am completely impressed with my progress. Everyone is really friendly and show that they truly care. I feel blessed to have found a place that can fix your brain . They have the latest equipment and the talented staff to compliment all of the different processes. I just wanted to thank Genesis for all that has been done so far. When I do complete the rest of my therapy I will post an update of my progress. Thank you and God bless. I want to thank Dr Majoranna for getting me in immediately after the accident, to see Dr Gleis, he is an angel in disguise. I had torn disc's in my neck and my brain had more than 20 bleeds and was swollen from impact . Affecting my motor skills and speech.. Dr Gleis Immediately got me in for brain and neck scans and mri . He then treated me with steroids and a series of shots in my neck to reduce the swelling . That was key to starting the healing process. As of this week I saw Dr Gleis for my follow up treatments, and again he flexed his angel wings . He delicately placed shots in my neck of exosomes. My right arm has been almost completely numb for months and as he was putting the shots in it seemed to reduce the pressure and ,I started getting feeling again. I'm excited for the future. I also want to thank Melissa for all of the prep and followup. Again the Team at Genesis is exceptional. Thank you.. I'm forever grateful, Michael HydePosted on Julie AdairTrustindex verifies that the original source of the review is Google. I can’t say enough good things about Dr. Gleis and his staff. After my car accident I was so confused and not sure what type of medical treatment I needed. All I knew was my body was hurting and had a non-stop headache. Melissa, his medical assistant was the absolute best. She was able to get me in the office the next day. During my first appointment, Dr Gleis and his MA Melissa spent over 2 hours with me, preforming tests, asking questions and answering all my questions. He was very professional, kind and patient. He actually listened to me with intent and patience, never did I feel rushed or brushed off, I felt heard and seen. Dr. Gleis was able to prescribe me some medications to help with my symptoms while we figured out what the root cause was. There was always a real person answering the office phone and I was able to get a hold of Melissa, the medical assistant in real time! They were always available to me whenever I needed. I can’t thank Dr. Gleis and his team enough. This is how healthcare should be! 100% recommend him. 10 out of 10.Posted on Jacqueline ShumanTrustindex verifies that the original source of the review is Google.

They were looking forward to my arrival. They knew my me.before I spoke a word. I highly recommend GBI.Thank you to Mellissa and Dr. Gleis.Posted on cfeaser94Trustindex verifies that the original source of the review is Google. Dr. Gleis and his MA, Melissa, were the first to see me at Genesis. Conducting a thorough evaluation of my present day conditions, they’ve been nothing short of impeccable right from the start. From their warm demeanors, thoughtful understandings, and precise knowledge of their practice. Gleis speaks with integrity and seeks to treat the root of the problems to dissolve the symptoms that persist and make life difficult. Melissa and Dr. Gleis continue to bring clarification and solutions to every problem poised. Genesis upholds a staff that is forward facing, kind, compassionate and knowledgeable in a field that can become weighed down and disheartening, with Melissa and Dr. Gleis being my first step through the door at this practice. I would strongly recommend this practice and these providers, all across the board, at genesis.

Learn More About Each Diagnostic Test
Want to understand the science of why our diagnostics catch what others miss? Here’s how we uncover what’s really going on in your brain:
qEEG Brain Mapping
This is our starting point. It shows us what areas of your brain are overactive, underactive, or working just right—providing the GPS to design your treatment path.
Videonystagmography (VNG) & Balance Testing
Helps detect issues in your vestibular system (inner ear and brain balance centers) that may be contributing to dizziness, instability, or coordination issues.
Oculomotor Assessments
Tracks how your eyes move and process information—key for anyone dealing with brain fog, TBI, or performance issues.
Cognitive Performance Testing
Measures speed, memory, focus, and how efficiently your brain makes decisions.
MRI Review (if needed)
While our focus is on function, we also review structural imaging like MRIs if our Neurosurgeon requests this, giving our team another layer of insight into what may be affecting your brain health.
Consultation with Functional Neurologist
We take everything we've learned from your diagnostics and sit down one-on-one to explain your results, answer your questions, and design a fully customized treatment protocol for your brain.
Each diagnostic is non-invasive, deeply informative, and reviewed by our full interdisciplinary team. It’s not just about what’s happening—but why it’s happening and what to do about it.. Each result is reviewed by multiple members of our expert team. Each one contributes to a personalized roadmap to healing and performance.
