Jeff Alexander at Cisco's local Englewood office didn’t get good grades in high school. “With a 2.0 and not too many college recruiters banging on my door, I joined the Marines,” Jeff explained to a room of high school students. After graduation, he went to basic training, took a placement exam, then started computer science school during his service with the Corps. Jeff studied for his first Cisco certification by flashlight on the back of a humvee. He returned just as the dot-com bubble burst, so he lived with family members while he pursued more certifications.
