Make Hyperlink to Internal “hidden from nav” page

Hi, I am trying to make a page that will not show up under the main nav as a sublink or anywhere else for that matter. I do need to hyperlink to this page from another page though. Does this make sense? I am using wordpress because the client wants to update the pages without having to have to contact us for these updates. This site is not used as a blog (no comments or outsider posts) but as a “static brochure site”.

Thanks so much!
