About Us

MCP Investigations & Security believes that it takes a special company with special people to be able to provide the sense of security and safety our clients require. We believe in paying our agents a better than average starting wage with growth opportunities, continuing education courses and providing them with the necessary training and equipment to keep our clients happy. Most of our employees are required to have some sort of law enforcement background along with military experience or some equivalent in education and experience. Our agents are required to pass a thorough background check and drug screening.

Our founder, John Mackey, has set the company standards higher than most other companies doing business in our field of work. Although there are some fine security and protection companies within the United States, we believe none of these companies have set their standards higher since the turn of the new millennium. With a new century and a greater risk of security breaches; a better trained, disciplined, and equipped security force is required to keep you, your business, and your employees safe and profitable.
