John Greeson John Greeson, Sales Manager – Texas and New Mexico

John is highly experienced at determining the security needs for a facility and fitting those needs into the available budget. As Sales Manager, he reviews all prospects and trains our salesman to understand how to best meet our customers needs. John has a unique advantage as a salesman in that he started as a technician. During that time, he gained knowledge of not only the products that Guardian offers but the difficulties that an installation may offer. Knowing that every job site is a little different, his experience helps him to offer the best solution to each customer, based on their circumstances. He has been with the company since 2011 and has experience with all areas of security that Guardian offers.
