Instructor Bio
John Christopher is a Technical Instructor that has been in the business for 25 years. His first experience with information technology occurred in the early 90s when he ran an MS-DOS based BBS(Bulletin Board System) as a System Operator. In the late 90s, after working with Windows NT 3.50 performing backups for Regal Group, he decided to get Windows NT Microsoft Certified.
In 1998 he got his first Microsoft Certified Systems Engineer and Microsoft Certified Trainer certification. Shortly after getting certified, he began working as a Junior Administrator and Instructor for Knowledge Alliance. From there John was able to become one of the first people in the world to gain an MCSE for the Windows 2000 operating system and he began teaching full time for a company called Productivity Point International. At Productivity Point, John got Citrix Metaframe certified and began teaching Citrix along with Microsoft classes. Productivity Point began experiencing financial troubles and John moved on to work with another training company in 2001
For many years at the training company in Atlanta John was the network administrator and held the title of Senior Technical Instructor for the company. John designed and administered their network from the ground up, going from a single floor in a single building, to multiple floors in multiple buildings and locations. He furthered his certifications, gaining the MCSE for 2003, 2008(MCITP), 2012, A+, Network+, Security+, Exchange, and CCNA. Along with his Network admin duties, John taught hundreds of students during his 11 years for the company. During all his years of training, John has had the honor of doing lots of classes with the military, along with quite a few classes within on-site military bases. In 2012, he decided to break away from the company he had been working for and do consulting and contract teaching. Currently, John gets hired by many different training companies to teach technical training classes all over the United States. He is also hired as a consultant to go into companies and work on their networks and implement, along with troubleshoot real world scenarios.
