Dr. Brent Lang was my orthodontist for about a year and a half. I had started Invisalign treatment in a different city, and then transferred to Dr. Lang’s care. Overall, I found Dr. Lang and his staff to be competent, friendly, and fairly priced. That said, I didn’t find them to be outstanding. My visits with Dr. Lang were usually fairly brief(I’d say under three minutes of facetime for each $ 150 check-up), and he basically made sure nothing was going horribly wrong. But the last part of my Invisalign treatment did not turn out as expected, with my teen tilting inward at an unfortunate angle. There may not be a whole lot they could have done about this, of course. Dr. Lang described how conventional braces could be used to correct this problem. I corresponded with Dr. Lang’s team for a while as I considered this treatment; on one occasion they took a second promoting to answer my request for a wrote, and on the last occasion they never responded to me at all. Since I was moving soon, I decided not to start new treatment. In all, I can recommend Boulder Orthodontics as a good, competent team, but I would also advise that anyone considering orthodontic treatment for themselves or their children seek a few different opinions before making a decision.
