How to access/edit the bottom part of the HOME page

The theme I have is Highend. I created the website awhile back. Now our clinic relocated and I’m trying to change the address on the bottom of the page. Please note that I’m able to edit any and everything in the body of the website. I’m talking here specifically in the black part of the Home page in the bottom of the page, which is **not** part of the rest of the website (it appears). I went to edit the theme proper, and I could sort of get to that section through there; I can change (if I wanted to) “All rights reserved” in the very, very bottom, but I cannot get above that (still the bottom (black part) of the page but a little above the very bottom. In that part of the page there’s LINKS, there’s CONTENT, and there’s THE ADDRESS of the place across the page: it is THAT part that I cannot edit. Somebody please help. My phone number is 703-677-1522. And in case you want to look at the site, the URL is AcupunctureHealthCentre.com Please note that “center is spelled cenTRE and **not** cenTER.
