Colleagues describe him as "Marcus was my all-time favorite manager. We were thrown together after a restructuring and thought it was going to be temporary, but it became long term. Even though he was in middle management with only one person reporting to him at the time, he was very driven and active in practically anything he could do to drive profit for the company. Since that is my mind set and the way I operate, we became best friends. He was excellent at bringing in talent from the diverse departments to from teams to complete projects like building a private SaaS environment with highly complex customer security requirements and audits within a very demanding time frame. If one group was late on their deliverables, we would volunteer to help in any way we could to keep the task on schedule. This the way we would operate on any task assigned. He became the driving force that kept the entire IT department customer focused and on schedule, when it came to delivering to the customer. He is one on a short list of people I admire most.", "Marcus is a hard charger, and intelligent worker. He isn't afraid to jump in and get work done, and isn't afraid to learn something new, and share what he knows with others. Marcus is also a team player.", and "Marcus is a bright forward thinking individual. During his time at the unit, Marcus was continuously sharing his military and civilian experience including his technical knowledge with other Soldiers. Without a doubt, Marcus is driven and wants others around him to succeed. He continuously pushes himself to learn and adept to the industry changes. He is a professional and has the confidence required in making difficult decisions. Marcus has never approached problems as roadblocks but as new challenges to experience. Without hesitation, I give Marcus Vaughan my strongest recommendation."
