Brian was awesome - GIVE THAT MAN A RAISE

Brian was extremely friendly, most of all very very helpful. As the facility and grounds manager I get pulled in many directions. I was running late and Brian came in and started to get to work. When I arrived he debriefed of what he was able to get done and what our facility needed to do, such as change a few dead batteries in exit signs etc.. In my opinion Brian not only showed he cared as a technician but displayed the type of professionalism that Guardian surely would be proud of.
