Dr. Colbert was selected as assistant principal of Mundy’s Mill High School (MMHS) in 2003 under the leadership of Dr. Anthony W. Smith. During his tenure at MMHS, he was instrumental in preparing the first class to graduate from the newly constructed school.

Driven to nurture a class of students from 6th grade to graduation, Dr. Colbert was appointed principal of Lovejoy High School in July 2009, where he served for seven years. He is one of the few principals in traditional high schools who is fortunate to have guided sixth graders to graduation with the Class of 2013.
