“I would like to send this letter to express my gratitude and appreciation for the remarkable job by your employee. It was not the first time that we have hired guards, to secure our parking and integrity of our property. However, it was the first time that we are completely satisfied with the services of your employee. He always showed up to his job on time, or many times sooner than his actual time. And he stayed till end each night. I was very impressed with him; something that I cannot say about our previous guards. Above all, I like to appreciate his work and he did not reduce his sincerity and commitment to the job.  For all that to thank so much.”

“Thanks for sending your security officer to this building. I was reviewing his reports and this is the type of reports that tell me when a Guard cares and knows what he is doing. He was very descriptive about the activity and it all sounds about right. I like to request him to stay with us at this property. Please let him know we are happy with his reports and this is the type of reports I like to see. Thank you very much!!! Let’s keep it up!”
