What I’d really like is for a person to be able to click “Memphis” and then only categories and posts pertaining to that location show up.

No,

The theme I am using is called KnowledgeBase and on the top it has 3 links, each by location.

“Memphis” – mysite/sample-page/memphis/
“Cleveland” – mysite/sample-page/cleveland/
“Milwaukee” – mysite/sample-page/milwaukee/

The problem is no matter which link I click I basically get an identical blog page which has all of the categories and lists every single post.
