Grant takes you step by step through what he finds and what the best option is. He'll even show you (if you're interested) with a live video.
He has a separate teaching degree because this gent really is passionate about his work.
As for the quality of his work quite outstanding.
I don't care to piss in people's pockets but when you have recommended to you a dentist with more superlatives than you'd find in a dictionary and he does live up to being an outstanding dentist - I think that deserves being recognised.
