We use him. He isn't too bad, a few problems, but nothing that would recommend you driving to another county to another ortho. I think his office in California is only open on Thursday so if you have an emergency, you will be driving to Waldorf to get it taken care of... say for instance a wire breaks. My #1, who has the braces, is the biggest baby when it comes to any slight discomfort at all, and they get him in rather quickly.
