I’ve been coming here for almost 2 years as an invisalign patient. I received my referral from a coworker & friend. There are 4 offices(Greenbelt, Annapolis, Bowie and Gambrills) but Greenbelt has been my office of choice. I started with Dr. Languth(no longer there due to the spouse having a job transfer) and have been seen by several of the Orthodontists and Dental Assistants in the practice. — everyone is very professional and nice. From the start, they explained the process and what I could expect, and that the price included refinement and retainer. It was supposed to be about 16 – 17 month procedure, however, no one predicted the problems that my stubborn #22 would cause by refusing to budge from its position. Although, things haven’t gone exactly as I had hoped, I am pleased with the results to date.
