Between 769px - 777px, banner text is broken

As you can see here, there are some weird stylistic things happening with the banner text at certain widths of the website. This doesn't happen on pages where the banner text is quiet one word (and the homepage), but anything more than that, there are things like this.

It's really bad on the Volunteer Info pages (this is only one example)

with absolutely no debugging or context, this looks to me like a possible solution could maybe be found by tweaking line break/line height settings, however, I suspect the underlying issue is that these banners were meant to be used for the company logo, not for page titles (which should be located at the top of each page's specific HTML file inside <h1> tags).
