I know he has helped people so don't mean this as rude but there is something very wrong with having a 2 year waitlist to me and now the people who have been waiting to see him for a year or two are not going to be seen by him because he is retiring. If I had been waiting that long and was told now I would not be seen by him I would be so upset. Out of curiosity when did they say he is retiring?
I hope you get relief from his replacement of course.
