entire site is WP- how to get Blog section to show Posts?

Hi-

You guys have been a tremendous help so far, but I have one more question.

I’m using a custom WP theme for my entire website. I have a blog page that I’m trying to get to show blog posts but am having issues.

I’m a little confused on where to look in the dashboard to make the appropriate changes.
Here’s the blog url: http://www.dental-intelligence.com/blog/

Thanks!!!!
