Dr. Michael Kuhn!
Go to Dr. Kuhn! He's done all three of my daughters with great results. He's great with appointments and has offices in Waldorf and in Wildwoode shopping center. All three of my girls had braces on for about 18 months, followed by retainers (invisalign) that they wore until they were worn out!
Kaplan is too old and old school for all the newer ortho techniques. I would definately stick with Dr. Kuhn.
