We had a wonderful experience with GTR. They came before our contracted time because we were new customers and Rogelio (apologies if I misspelled) was personable and engaging and took his job seriously. We needed a security presence for our festival and all of our patrons felt safe. I will work with GTR in a heartbeat again. More...
