Dr Harwell is the best!! Never rushes and always listens! I hope you never need the services of a neurosurgeon. But, if you do, Dr Harwell’s expertise and great care are all you will ever need. I recommend him highly !! (Jill, Kristin, Lisa and Dari are top notch as well and get 5 stars as well!!

They were informative, efficient. Preop, surgery & postoperative all scheduled then. Got the back brace then also. Other than I'm not crazy about surgery , it all went well.

Dr Thamsbuswamy is the kindest, most knowledgeable neurosurgeon who cares about your total quality of life that I've met in my 66 yrs. He treat patients the way he would want his family cared for. He will take as much time with you as you need, without worrying about how much time you've been there.
