Site Title Not Displaying in Original Size

I’ve searched all the forums on how to change the site title on my site, and every little bit of code that people keep offering doesn’t do anything. I’ve gone into the header, the css, deactivated various plug-ins…

I’m using ZeeFlow theme and here is the site: http://www.coastalrim.com

I would like the “Coastal Rim Properties, Inc” at the top to be the original theme title size.

Thank you.
