We have three facilities in Denver where True Security of Denver provides security guards. They are sensitive business locations, and TSI has not only been superior to security guard services we've had in the past, but they have been superior across the board including administration. They are consistently on time for guard duty, do their job, and are friendly to the staff on location. The admin staff is great to work with as well. Good bunch, and I highly recommend their services to others in the Denver area.
