What Patients are Saying About Boulder Neurosurgical & Spine Associates

  • Dear Dr. V and Staff – This note is a long time coming. THANK YOU for helping me get my life back and getting my back to marathons. I ran my first post-surgery on October 12, 2014 – 5 ½ months after surgery. It was slow, but it was pain free and one of my most memorable to date. Coming to Boulder was the best decision I’ve ever made. Thank you for truly understanding athletes and giving us hope!
    — Danielle H.
  • This thank you is way overdue. Dr. Nelson is the greatest surgeon in the world!! I had back fusion surgery two years ago this month and I got my life back. I originally went to see him for a second opinion about my back problems. I had been suffering for a few years - not able to stand up straight for the first hour I was out of bed every morning, chronic sciatic pain, and not able to walk but a few steps before resting. Dr. Nelson offered me a more reasonable surgery plan than I heard initially and I immediately felt confident that I had found my answer and my surgeon --- and nothing has happened since that day to change my mind. My surgery went great – I can honestly say I have had no pain since the minute I came out of recovery. I was diligent with my recovery instructions and physical therapy. My biggest fear now – 2 years later – is that I’m going to forget someday to be grateful for Dr. Nelson and Sara and Mike and Jennifer. I never want to take being pain-free for granted. Thank you all so much!
    — Anna S.
  • Thank you for the wonderful care. I had surgery on Oct 2nd and everything went well. Dr. Rajpal was friendly and caring. He explained things so I could understand. His staff is also great especially Erica the PT. I am about nine weeks out now and feeling great. This is a life changer!
    — Harvey W.
  • A note of thanks is due to Dr. Beasley, not just for taking my case and taking care of me, but for looking me in the eye yesterday and making me understand that being post-concussive doesn't stay crummy forever. I've been wanting to get back to feeling like myself for several weeks, and now I actually believe that might happen. That means a lot. Thank you, Dr. Beasley. You rock!
    — Scott P.
  • Dr. David Shafer and Stephane are awesome! I've been in a lot of pain which leads me to being grouchy. I wanted to thank the two of them for helping me get to the bottom of my pain. When I walk into the office, Stephane always greeted me with a smile and such a positive attitude. It helps me to know that she genuinely cares. Dr. Shafer is so kind as well and really cares about my pain and is trying to get some pain relief for me. I can't thank them enough! I've been a patient since Jan. 2015 and thanks to the two of them, I'm feeling a little better.
    — Jody R.
