Center text in text widget

I’m a wordpress newbie, just getting started, so thanks in advance. I also don’t know a lot of html…

I’m using a text widget on a site I’m just starting to work on, Regulatorypro.com. I’d like the text widget to serve as a footer for contact info, and I’d like that centered on the page. I tried a simple “center” tag which didn’t work, and I’ve poked around a bit looking for the appropriate place to find the html code itself in the Editor–to no avail. Can anyone help? I’m using WordPress 2013 for now. Thanks again!
