Getting blog to show as link in page menu

Any idea how I could go about this?

Currently I have the website set to show my blog by default, but what I’d like to do is keep the theme the same, and add a page to the menu up top that if a visitor clicks on it, displays my blog.

I like the set up and look of wordpress so I wanted to keep my website using it, but add pages with information on there, and link the blog entries to one of those pages. Does that make sense?

Is there a way to do that? I’ve searched quite a few of the threads here and can’t really find an answer for this particular dilemma. I’d appreciate any help. Thanks so much. Below is the website link.
