in Mooresburg, TN |
Complete waste of time! The staff was nice but the doctor was condescending, arrogant and somewhat rude. Runs the business like an automated carwash. The nurse interviews you for 30 minutes the doctor comes in and spends five minutes with you and goes onto the next patient. I was in a plane crash 30 years ago and wanted a full evaluation of my entire spine. I provided MRI from the VA. Zero communication between doctor and staff. (probably because he knows it all already) AVOID AVOID AVOID
in Greenville, TN |
I just recently had a Total Knee Replacement done by Dr. Grimaldi. My pain level before surgery was way up there. I couldn't sleep more than two hours at a time. I feel like my recovery from surgery has went well. My pain level after surgery is rare. I barley have any if no pain at all. I am glad he did the surgery. I feel like I have gotten my life back. I would recommend him to anyone.

I recently had 3 amputations on the tips of my fingers. Dr. Grimaldi researched and said i had Burger's disease, when other doctors had diagnosed me with raynaulds syndrome. I feel like the surgeries went well and I am almost 100% back in a month. I would recommend him to do anyone else's surgeries in a heartbeat. I had my surgery on December 21st, and he called me Christmas night to check on me and see how I was. That was very impressive.
Jefferson City, Tennesse |
I have had both of my knee's replaced by Dr. Grimaldi. My level of pain in my right knee was a 9-10. After surgery, I have no pain. I feel like I am getting my way of life back. My left knee pain was about a 7, after surgery it is only 12 weeks so it is intermittent. I would recommend him to anyone. I was also impressed that Dr. Grimaldi called me at night, at home, to check on me after surgery. I really appreciated that, and that is almost unheard of.

in Blountville , TN |
For 3 years I had been treated as though was only after pain meds. Dr. Grimaldi found a fracture in my back that no one else had found. He told me if only 1 Dr had asked if did gymnastics when I was younger then my problem would've been discovered long before he found it. My surgery went great with scar only noticeable if you are looking for it, and as have huge tattoo on my back that he had cut down the middle that alone is impressive. He took the time to answer all questions my fam had.Awesome
