"Dr. NaPier and his team do what they say they are going to do. His team is cheerful and caring. Dr. Napier’s diagnosis was spot on. He listened to me and explained what he thought was needed to relieve my pain. After my surgery I was able to stand up straight and walk, day one. The back pain and leg numbness was gone. Eight weeks after surgery and I feel great."

"I was originally going to have my spine surgery with UC DAVIS but decided to get a second opinion. I am so glad I did! Dr. Napier is a phenomenal surgeon. His procedure was less invasive than what was originally going to be done and my recovery time was almost non existent. Spine surgery is scary. I had an artificial disk inserted in between my L5 and S1 thru my abdomen. Then I had two rods and four screws inserted in my back. I am 8 weeks post op and feel better than I ever have before. All pain is gone, I'm bending and twisting, AND I'm living a much healthier life now. I am blown away by my results and I can't thank Dr. Napier enough for what he's done for me. If you are looking to have spinal surgery, I would recommend Sierra Spine Institute 100%! Everyone is kind, caring and supportive and the process was so easy. Thank you so so so much Dr. Napier!!!!"

"I had, what I think is normal, hesitations about getting surgery. What if something went wrong? But, I basically was not walking more than a couple of very painful yards and was wheel chair confined. Dr. Napier really listened to my concerns. He didn't rush. First, we tried non-surgical alternatives, which worked for a bit. However, it became apparent, a longer term solution was needed. He was very optimistic surgery would help. He explained, in a very easy to understand language, what would happen, what to expect and the potential side effects. The shooting pain was gone immediately after surgery. I did have pain from the surgery itself but was much better after a week. Now, 2 months later, I am pain free. I was mentally prepared to be disabled for the rest of my life. It is a miracle and Dr. Napier is the miracle worker. Thank goodness he went into this profession."

"I suddenly started experiencing severe and incapacitating back pain in January 2022. It was the worst pain I had ever felt in my life. I was completely crippled by these attacks which were crushing nerves between my vertebrae and making normal day to day activities impossible. I spent large parts of the day in bed. I went to Dr. NaPier and agreed to major fusion back surgery. Immediately after surgery my nerve pain was gone. Now, 3 months after surgery, I have my life back thanks to Dr. NaPier. He is a patient and understanding doctor who carefully explains the issues and what he will be doing to correct it. He also has a top notch staff working for him. I can't say enough about how well they have taken care of me. If you want to get out of pain and get back to living, I highly recommend Dr. NaPier."

"I was very confident in Dr Napier after my first consultation. He explained my MRI and my options in terminology l was able to understand and feel positive about my decision for surgery. His office staff is also very professional and accommodating. They were completely on the ball from start to finish. I highly recommend Dr. Napier. I am finally able to move my neck with much more ease and less pain"

"Dr Napier and his staff have been excellent. They took great care of me and best of all, fixed my back."
  • April 25, 2022
"My experience with Dr. NaPier was excellent. He took a conservative approach to my surgery and didn’t do more than he needed to to alleviate my pain. The procedure itself was fast and comfortable at the surgical center. My recovery was far easier than I had expected, I had so little pain, I still can’t believe it. I am 7 weeks post surgery when posting this and just about 100% of my pain is gone. I am so glad I had this procedure when I did and didn’t wait. I would highly recommend Dr. NaPier and Sierra Spine Institute."

"Dr. NaPier and his staff were top notch. The entire process for surgery was very organized. The post-surgery experience was also excellent. Dr. Napier was very professional, yet personal. He explained things terrifically, we never felt rushed, he took the time to answer questions. We highly recommend him. By the way, the surgery was a success!"

"Must admit, having this surgery was the worst experience of my life but that was my condition. The care by Dr NaPier was superb, so professional and his staff is outstanding. Highly recommend them to anyone who would require their services"

"Life Savers! All I could do was lay in bed getting weaker by the day. Every move was lighting bolts shooting down my legs. When Dr. Napier looked at my MRI scans he immediately had me admitted to the hospital for surgery the following day. It's only been 5 weeks. Those lightning bolts are gone. Each day is better than the last. The surgical site is tiny and healing fast. The pain from the surgery is nearly gone and sciatic is hardly noticeable. THANK YOU ! ! !"
