I want to sincerely thank each of you for the outstanding care you provided during my back surgery. The surgery went great, and I truly feel 100 times better. Dr. Harvell, your skill and precision have made a tremendous difference in my quality of life. I am deeply grateful for your expertise and the excellent outcome. Mark, thank you for your calm and reassuring presence as you administered anesthesia. In a moment that requires complete trust, I felt completely safe in your care. To the nurses and staff, thank you for your professionalism, kindness, and attention throughout the entire process. From pre-op to recovery, I was treated with compassion and respect. Because of my experience, I would confidently recommend anyone needing neurosurgical care to come see you. The level of professionalism and teamwork you provide is truly exceptional. With sincere gratitude, Jody Wight

I have no I Idea what happened. Everything was great. My Neck surgery went great (so far) Dr. Harwell and his team seemed to be responsive and care. Not long after the surgery in 2023, the whole place just fell off. Scheduling is a nightmare,No one follows through with any referrals leaving the patient to coordinate most imaging, pt or any other type of out of office procedures not done by them. I gave them almost 5 years. The last two years have been the worst. I had to seek care from another specialist. Maybe they just had too many patients. THE STAFF NEEDS TO GO! I HAD A SPINAL FLUID LEAK AFTER A PROCEDURE. NO ONE CONTACTED ME TO HELP AFTER COUNTLESS ATTEMPTS TO GET ANY HELP. I ENDED UP IN THE ER AFTER A WEEK OF NOTHING. ITS BEEN 3 WEEKS AND MULTIPLE CALLS AND YET, NOTHING. DO NOT GO HERE! I do not take narcotic pain medication or require it, so do not think this is just someone mad about not getting pain pills. This has been a multi year venture with a cervical fusion. Please heed my advice. Edit, Yes my calls were returned. But only after I asked for the board of directors number. All of the sudden. The calls and emails started flying in. So, it took 3 weeks, rattling cages and posting a google review to get a response. I will say the same thing I said to Dr. Harwell and your office manager Dari. "I have no interest in or time for rehashing a week of my life defined by pain and fear. My only hope now is that this ordeal leads to actual systemic changes so nobody else has to experience what I did" (John Oakley.)

Dr. Harwell is the best surgeon I have encountered being I have had 3 neck surgeries and 7 back surgeries in the last 37 years being I have had a few surgeons. Dr. Harwell has done one neck surgery and also removed the battery that was for a stimulator cord I currently have in my back. He is very compassionate in what he does and explains everything without leaving any questions. I highly recommend him for whether it's your back or neck or both. I will actually be contacting his office in the near future for further information on my back.
