Teaser Box Border

Hello,

I was wondering if there is a way to get a border around the entire teaser box element, here is my page with the teaser boxes: http://69.195.124.220/~synergyn/services/

As you can see, I was able to get the border around the bottom of the boxes, but I would like it to go around the photos as well. Is there any way to accomplish this? Thanks.
