Need css code to disable summary block converting my image titles to all upper case.

Site URL: https://www.blueridgeresearch.com/#ourteam

The image titles in the summary block are all showing as upper case. The titles are not actually all upper case but the summary block converts them to upper case. Does anyone know a bit of css code to make them upper and lower case? Thank you for any help you can give me.

You should be able to change from uppercase to  capitalized in design/site styles/summary block title fonts. 

Thanks, Derrick. As usual I was making it more complicated than it is!! Note to self - First look in site styles before you customize.
