I've created a couple testimonials I've decided not to put the clients company on my testimonials, since I do a lot of white label work.  The issue is that even though I do not have the "Client Company" there still appears to be a comma before the name of the client.  

Can you tell me where in the theme files I can find and remove that? 

Thanks for the update!!

If I update this code then update the theme, will that information be overwritten? 

Thank you so much!!!
