Malo - It was probably not intentional on his part and he may in fact just be occupied with his more needy patients. As a CG, I haven't had experience with Rad Doctors, but I have had some experience with a couple of dentists I have, one who is a "Mr. Personality" type, lots of chit-chat, personal references to things we have in common, etc. but I had no real confidence in his experience. When he referred me to an Endodontist for a root canal, the Endo. was pleasant but very cool and absolutely no chit-chat. His treatment was phenomenal, tho' and made me actually look forward to and enjoy the experience of the next root canal! (I had two with him) So I think I would rather have the benefit of the expertise over the personality. If you can have both, then that is the ideal, of course. I'm sure others will be able to give you more personal experience re their rad onc.
