Quote shortcode having spacing issues

I am using the shortcode for “quote” and there seems to be a spacing issue. Text is overlapping each other and I don’t know how to make it stop.

Here is a link to the page with the issue. http://successinhighered.com/navidimonk/setting-standard/clarity/

Please help!
