"I’ve have had the pleasure of knowing Mark Kessler now for about one and a half years.  Mark would be a valuable asset to any team.  Not only is Mark a hard worker, but he is adaptable to any environment and will do just about anything to help the team.  In addition to his job as a Systems Administrator, I’ve seen Mark debug our alarm system, reprogram the phone system, even clean the walls of graffiti before the boss comes to work, and the list goes on… Many of the tasks I listed were performed by Mark after hours or on the weekend which further displays his commitment to the team.  In addition to managing the company servers, Mark has helped me with numerous issues with my own computer.  On one occasion, Mark noticed I was frustrated with the latency of my computer so he moved me aside kindly and cleaned up several items on my computer that were slowing down my performance.  This sped up my computer greatly and it allowed me to perform my day to day routine more efficiently.  One of the important ingredients to any team is chemistry.  He has a great personality and gets along with everyone.  When Mark walks in the door, his smile brightens the room.  I appreciate his technical competency and his personality.  Mark is a rare gem."

Jennifer Wiehl

“Mark is one of the best Systems Administrators I've ever encountered.  He takes the time to listen to any issues and his response time is phenomenal.  Mark speaks to you in ways you can understand about the issues you are having and works quickly to come to a resolution.  He also has amazing follow up and you know by interacting with him that he genuinely cares about his work.”

Surjit Gish

“Mark is a solid IT guy, to be sure, with a diverse skill-set and deep knowledge in a wide range of topics, but there's much more to him than that. Phrases like "team player" and "positive, can-do attitude" are overused to the point of being meaningless, which is unfortunate, because these perfectly describe Mark. For real. Mark is thoughtful, kind, and engaged in his work... a real joy to be around, in or out of the workplace. He truly brightens the days of those working with him.”

Miguel Pommier

“Mark is a highly motivated individual with outstanding work ethic. He is dedicated individual with an integrity that you do not find very often. I have worked with Mark on several projects and have been constantly impressed by his innovation and creative ways of addressing issues.”

Walter Munoz

"It was a pleasure working with Mark at HP. We were on the same support team and he definitely pulled his own weight and them some. He is motivated about his work and goes the extra mile. He was an excellent person to have on a team and collaborate with.”

Christopher Ballas

"I have had the privilege of working with Mark in his role as Systems Administrator for, 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."

Tamara Dumont

“We appreciate Mark's integrity and his ability to get the project done. He assessed the need and implemented the solution without going over budget, as a matter of fact he was able to solve our problems in a superior fashion under budget. Mark was easy to work with, never spoke down to us or spoke in a way we would not understand. I highly recommend Mark.”

Rob Miller

"Mark Kessler is without a doubt the most reliable hard working ethical person I have met in my life.Mark goes way beyond your common everyday employee, he cares about everything he does and this is the kind of person any employer can benefit from.  Mark worked with us for almost 5-years and I know anyone looking for a dedicated hard working professional to work in Facilities/Telecommunication work, Information Technology projects.  If you have any questions please email or call me."

Nathan Taggart

"I can proudly recommend Mark after working with him for years in his position as a Server Administrator for  Mark's oversight over the user accounts and workstations throughout multiple office buildings is personable and timely.  When needed, Mark would organize contractors, vendors, and service personnel; he has a rich list of contacts and always knew who to bring in.  Mark is a charismatic, outgoing professional who readily identifies problems and provides solutions.  He seamlessly handled a wide variety of facility issues as well and works hard to keep the "behind-the-scenes" work of managing the offices invisible to the tenants.  Mark is the kind of guy you can have take care of practically anything: from computer networking, to desktop troubleshooting and coordinating HVAC maintenance...  Mark is my first point of contact."

Deanna Pennock

“Mark is a consummate professional.  He takes seriously his responsibilities - which, in my experience alongside him, ranged far and wide, from sysadmin to facilities management and beyond.  Mark is multi-talented and highly skilled, as evidenced in his background.  It's worth noting that he uses both his intelligence and sense of humor to effectively tackle challenges; I saw this quality positively impact morale on numerous occasions.  Mark is also remarkably motivated to accomplish everything asked of him.  (Of course, most of the time he simply anticipates what is needed and jumps to act.) There are few others who match Mark with respect to depth of character.  His ethical compass is well-rooted and he is trustworthy.  Furthermore, Mark respects his colleagues and is fair in his dealings.  As a colleague and friend, Mark has left an indelible impression, and I would not hesitate to work with him again; indeed, it would be a pleasure.”

Karen Carter

“I have known Mark for 4 years as an IT admin, Mark is very responsive to problems and things that need to be taken care of. Mark is a easy person to work with on projects that need lots of testing and talking to other vendors to see if right resolutions will work in the environment. He has partnered with the Dell relationship resolving these problems. The relationship he has developed with Dell gives him great pricing and service over and beyond what you may get when not having that relationship. Karen Carter”

Angela Arriaga-Simpson

“Mark is by far one of the nicest people I have met.  Working with him is a pleasure as he is always willing to go the extra mile in everything he does.  He is one of the most dedicated employees that I have encountered at a company.  Anyone that gets the chance to work with Mark will be not be disappointed in his work ethic."
