Mark Jacob

“My goal is not just for the students in my classes to learn, but to make it easier for them. If you enjoy learning, you’re likely to remember it. You learn when you’re having fun.”

Mark Jacob is a Cisco specialist, teaching ICND1 - Interconnecting Cisco Networking Devices Part 1 and ICND2 - Interconnecting Cisco Networking Devices Part 2.
Mark uses his current day-to-day experience as a network administrator to provide students in his classes with real-life scenarios and equip them with the knowledge required to administer TCP/IP networks built with Cisco hardware — and do it well.
Selecting routing protocols, setting up IP addresses and performing subnetting — Mark teaches students straightforward methods to accomplishing Cisco network administrator responsibilities. Students are amazed at how “easy” much-feared tasks such as subnetting can be once they learn Mark’s methods, and the proof is in their success, passing exams to obtain certifications.
Mark’s passion for engineering led him to the Information Technology profession after a career with the U.S. Postal Service. Taking classes on his own time and starting out as an unpaid intern, Mark has a drive that is clearly a bonus to students in his classes. A volunteer tutor of young students during his off-hours, Mark says: “I enjoy seeing the light go on in somebody as they learn. If I teach it to you on a Wednesday morning, by Wednesday evening, you can do it.”
