I think Dr. Jeffrey came from a professional teaching/ academic area. He told me everything i needed to know as if I were his student. May be he was a professor, if not, he easily could qualify. His explanation of how things around our mouth works are impecable and detailed.
He is also very careful, at least for me and very easy and fun to talk to. His office does the usual follow up including the 6mos call to your house/office or cell as needed. I highly recomend him. The only thing I notice as a negative is that his office is much smaller than i expected.
