From what I know, SIU is a terrific school. I think it is a gem hiding in a small town that not too many people know about. They consistently finish very high on the boards. Apparently, the last five years, they have finished in the top 10 of all schools on Part 1. One year they finished second. This shows that they have a sound didactic portion of the school.
The prof I spoke with said that he would put their students against any others in the country. I don't know about this, but that is what he said.
Very affordable living expenses and one of the most affordable tuition and fees in the country.
I have heard that their clinical education is their strongest part of the curriculum. From the SIU grads that I know, they agree with this. They have nothing but praise for the school.
Don't quote me on this, but I do believe that they have an endodontics specialty program and they have some sort of implant post grad program. You will have to either call or check out their website.
All in all, it is a very good program, especially for the price. This is probably where I will be going. Hope I helped.
