We love Dr. Greenberg!!! He’s great with the kids (very funny), spotless facility and always on time. We priced similar treatments with two other Orthos and he was on target. What I really love is that he’s always ON TIME. I know I mentioned it before…but when was the last time you could set your watch by a doctor? So if you work, or don’t want your kiddo to be gone two hours for a follow-up, he’s your guy. He also has after hours service that’s great. We were having a problem with my son’s expander and I was met onsite an hour later at their Frisco facility to get it fixed. Thanks for being awesome!
