Why Choose Us?

Upon accepting the position of Key Control Officer, I had limited experience with the Best locking system and found John Harris with Marshall Best Security was able to provide the additional training I needed. With John’s vast knowledge of our system, he has helped me solve many problems and continues to do so whenever I call him. It is just a pleasure doing business with John and Marshall Best. Thank you and we will continue to do business with a True American Company!

Once I started getting involved with the keys and the locks here at Sun Life stadium, I needed to work with someone who has great knowledge in that industry. John has proven to be the right person. He always gets me in the right direction about which product that fits my needs best. I would recommend Harris Security Solutions to anyone just for the simple fact that John does not focus on just selling a product to a customer but makes sure you get the best quality of products at the best price as well.
