Being new in a field can be a good and bad thing, sometimes you need to listen to what your gut is telling you and of course research research.
The problem he will have is experience, you can train and practice all you like but it's the experience of dealing with all kinds of different people, problems that can arise and of course the steady hand you get from confidence that is gained from years of actually doing it.
My honest advice is... "you should always go with experience."
What is your major interest in this doctor? Are you looking at any other doctors?
