Dr. Thomas's prices are fair. Especially for the orthodontic treatment itself. The retainers, should you happen to lose them, however, cost an arm and a leg. But I think that might be the case everywhere.
I went in with a very exotic case, that the 3 other orthodontists I visited told me I would need major surgery for. Dr. Thomas told me he'd like to try to fix it without surgery with his Damon system.
In two years, he fixed 100% of my underbite, and I would say about 90% of my crossbite, without surgery. I am very happy with the results, and my profile and smile can't even be compared to the way they looked before.
Solid guy, Dr. Thomas. If you're in the Poway/Rancho Bernardo area, I highly recommend you visit with him.
