Add custom fonts

I have a couple of custom fonts I would like to use in the theme. I've tried a couple of font plugins, but no luck. Is there any way to add or customize my font options? I'm looking to add some. (Brandon Grotesque Regular and Bold, and Calder Dark Grit) I would really especially like to add Calder Dark Grit as we use it in our logo and would like to use it for headlines. Thanks for any help!
