While my wait time was longer than 15 min, it was understandable-I had several sets of xrays and in turn saw the provider only a couple of minutes after the original appointment time.

Dr. Nielson is very kind friendly and patient. He made us feel valued and comfortable. He doesn't make you feel like a stranger but a friend. He listens.

*Dr. Neilson is a wonderful doctor. Very intelligent, and cares about his patients -
May 27, 2019
not only did he take care of my leg but he did so in a manner that did not make an issue of how bad the previous doctor had done the surgery. Dr Neilson also is an example of an excellent doctor but humble his only concern is how YOU feel. I have met very few people in life who measures up to this doctor and human being.

The physician assistant and Dr. Neilson were both very caring, respectful, answered my questions and developed a plan of care based on my input.

My appointment was at 10:00AM. I arrived at 9:30 (as I was instructed) for X-rays. At 11:05, I approached the receptionist to ask about the delay and was I told that the doctor was running 45 behind schedule. I was not taken into a treatment room until 11:20.

All through the process, from planning the surgery, through recovery Dr. Neilson has been exemplary. He took my concerns to heart from the beginning, he spent a good deal of time with my spouse after surgery to explain the whole procedure, and was certain to explain to me everything that happened. He did a fantastic job of getting this knee in place. I was able to walk without assistive devices after only 6 weeks of rehab and walk with no limp. He also made visits to me when I was admitted a week later to a medical unit for cellulitis, even though I was not admitted by him. I have already been asked who replaced my knee by another person who was going to make an appointment with him.

Your facility is impossible to navigate. I drove past the correct building 2 times before I realized that I had done so.

All services good with exception of receptionist. Doctor interaction and X-RAy team excellent.
#4. Receptionist poor did not look away from computer screen. Seemed angry.

Dr Neilson was not rushed during his time with me. I appreciate that he had and took the time necessary to be sure what he said and what I understood were one and the same.
