  • You’re in good hands! I had a disc replacement in my neck for pinched nerve pain I suffered with for 14 long months. Dr Harrison told me he thought he could fix my issue and he did. My pain left me immediately after my surgery and things went just as Dr Harrison and crew told me they would. I initially tried to avoid neck surgery...I guess it scared me to do... But I’m glad I did this and that Dr Harrison was my surgeon. He has a great reputation and it’s well earned. Thanks for freeing me from constant pain.

  • My first experience with him was back in 2/2018. I had fallen and injured my back pretty bad. Causing my left leg to go numb and weak. Fast forward 6 years later I go back with pain again and basically tells me it’s not bad enough to do anything. But while in the examination room he had a women I had never met. While he was talking to me and my daughter she taps his shoulder and shows him something on the monitor. All of a sudden he tells me there is nothing he can do for me so bye!!! Fast forward to now. After finding out through a different doctor that he Dr. Harrison took out bone in the area he cleaned out, I never thought anything about it, until now. Since April of 2024 until now I have done 2 MRI’S and xrays proving my back is collapsing. I have so much pain in my buttocks going down to the calf on the right side that I cannot sit for long periods of time and when I stand up I can barely move because I’m in so much pain and my leg will give out if I dont walk very slow and sometimes I need help. The other side hurts just not as severe. Because I have other ailments like fibromialgia that he doesn’t believe in, or because my knees were tender that’s what it must be not anything in my back even thought he showed me himself the results. My back is falling apart and he won’t help. Blew me off. Thanks for nothing. For a doctor to gaslight me or to say he won’t help after doing surgery on me before, is down heartening. I guess it’s my problem and on to a second opinion. From someone who is very unhappy with a doctor who is supposed to be the best.

  • I never had the chance to see Dr. Harrison directly, but my experience with his office was deeply concerning. I was seen by his assistant, Angela, who was kind.. but my serious concerns regarding cervical spinal stenosis, including lack of relief from physical therapy and gabapentin, were not addressed appropriately. When I expressed my fears about worsening health and progressive symptoms, I was terminated for being “too emotional.” The termination letter simply said, “find a new neurosurgeon,” which felt dismissive and left me without access to urgently needed care. Since being terminated, my symptoms have significantly worsened, highlighting that my concerns were valid. I had already suspected this practice was not going to help me, but they held the upper hand through the technicality of the termination letter, leaving me as a patient struggling to navigate a system that often does not advocate for people in pain or suffering. I hope this practice reconsiders how it responds to patients in distress and ensures that progressive, serious medical concerns are never ignored or punished.
