Swap div content for a page on the site rather than navigating to that page?

My explanation may be entirely confusing, but I’ll do my best.

I’m building a site that will have a lot of content light pages (like bios for staff) I’m wondering if I can display their simple pages on a single page without navigating to/reloading the page?

Basically, I want a navigation area where people will be able to click on a dynamic list of the names of the staff and rather than navigating to that actual page, I’d like to just have the content of a div on the page swap out. I have a feeling I could probably hack something together with an include command, but I’d like it to be more dynamic (ie – all the staff bio pages (simple text) could be created as straight wordpress pages rather than having to make them as individual HTML pages) and everything could be handled behind the scenes by PHP and WordPress.

Anybody have any suggestions as to how to make this happen
