I've been in and around the security industry for nearly 25 years now. Worked with, alongside, or for many companies in the Denver Metro area and honestly when it comes down to it, I have difficulty recommending more than just a select few.

I know Mark, and he is a solid security operator. You can't go wrong with his abilities, leadership, training, and experience in the field. No matter what needs you have, this company will fill them. Expect nothing but the best.
