Everything went smoothly! We have had problems with our PREVIOUS security firm over the past few years. The biggest problem is having them show up. Tri -County was there right on time each night. Very personable and as far as I can tell, they did a great job (meaning no incidents with our tents and contents). We will definitelt hire them again.

State Security Enforcement Agency is a great service at a very reasonable price. My security guard was on top of everything the entire night I needed him. No complaints.

I visit Denver a few times a year for business and have hired Sharp End Security on multiple occasions. Jason has been my appointed private security detail and I have been incredibly impressed with his professionalism and close-protection tactics on each and every occasion. I work in a high-threat environment, and Jason has always been able to mitigate potential risks and add a significant layer of security to my travels to Colorado during each visit. I will be working with Jason and Sharp End Security in the future. Cheers!
