"I have had the privilege of working with Mark in his role as Systems Administrator for PeopleFinders.com, a people locating and background check company. The nature of our work in the background check industry requires that we seek applicants with the highest caliber of integrity, professionalism, and discretion. Mr. Kessler exemplifies these traits and was an asset in this position, as I'm sure he will be for you.Mark is an exceptionally gifted, knowledgeable systems administration professional, who worked closely with senior executives to plan and execute many large network and telecom projects across multiple company properties. Mark was directly responsible for maintaining network connectivity and security, overseeing the setup and maintenance of our several-hundred-Iine phone system, and monitoring and managing all security equipment including alarm systems and video surveillance. Mark was the first point of contact for any network outage or business interruptions and he coordinated all response and repair situations with service technicians.While it would be easy for me to list a myriad of examples of Mark's technical savvy, I think that some of Mark's other traits are what truly sets him apart. Of everyone I have known and worked with, Mark stands out as having the most integrity. He is honest, loyal, humble, and dependable. He was routinely the first one into the office and the last one out. Mark worked tirelessly to ensure that his work took place 'behind the scenes' and that no one was impacted by routine, planned network maintenance or other avoidable nuisances. One of my favorite stories about Mark is of a day I found him painting over graffiti on our building. He had arrived early that day and found that someone had vandalized our property in the night. So, rather than have everyone see it, Mark got out a paintbrush and paint and fixed it on the spot! That's Mark, always doing what needs to be done.Mark Kessler would make a fine addition to your organization. He is one of the few people that I can recommend unconditionally. If you have any additional questions, or if I can share anything else about my experience with Mark, please call me directly at 916-266-0633."
