Dr. Nielson operated on my son's knee, and I liked him very much. He put us at ease both before and the day of the outpatient surgery. My only complaint isn't related to the doctor. When I took my son for follow-up visits, I never had a co-pay because the front desk said I had a credit balance. Now that we don't need to go back for follow up visits I called to find out if I still had a credit balance, and lo and behold I do-- several hundred dollar's worth. What they charged me for my out-of-pocket portion for the surgery was higher than what the surgery actually was, which is no big deal. What is a big deal is that I have to wait several months before they'll cut me a check for what I overpaid last year. Not real happy about that.
