I have two boys who have been going to see Dr. Alexander for 5 years. Their braces have been on for a long time because their adult teeth have been slow to emerge. We have found Dr. Alexander and his staff to be pleasant and friendly most of the time. The office can get crowded but it's clean and well-maintained. One of my sons has a medical condition that requires twice yearly MRI's of his head, in order to avoid artifacts it is imperative that he have no metal in his mouth. My son's brackets are non-metallic, and Dr. Alexander takes out the bands and wires before the MRI's, then puts them back after the scan. We had a hard time finding someone who was able to accomodate this request and Dr. Alexander has been great in this regard. Cons: Appointments not scheduled a month or more in advance can be hard to get, we've had to wait more than a week to get my son's braces back in after his MRI's. They allow for the breakage of two brackets over the entire duration of the braces, then you are charged. Many kids have their braces off after 2 years but my boys have had their braces on for longer than that. Once less than an hour after we left their office and we headed to another doctor appointment, my son's bracket literally snapped in his mouth, he'd had absolutely nothing to eat (there was no opportunity) and only a few sips of water, I was with him the entire time so I know. We called them and they got us in later that day to replace the bracket, but later, after another bracket broke, we'd exceeded the 2-bracket limit and the office manager wanted to charge us. I told her about the bracket that spontaneously snapped and she was very confrontational, told me flat out that that never happens and that my son had done something to cause the breakage. I started to get upset as I'd been with him literally every second and there was literally nothing. Dr. Alexander overheard the conversation and instructed her to let it go and we weren't charged. Overall our experience has been positive and I don't understand all the one-star reviews. I've referred three of our friends to Dr. Alexander and they have all been satisfied He is less expensive than some of the other orthodontists in town. If you are considering him I'd advise you to give him a chance and form your own opinion independent of the other commenters' opinions
