Mike Johnston represents Northeast Denver in the Colorado State Senate. Mike first entered education as a high school English teacher in Greenville, Mississippi, an experience that led him to write his acclaimed memoir, In the Deep Heart’s Core. After leaving the Mississippi Delta, Mike co-founded New Leaders for New Schools, a national non-profit that recruits and trains urban principals. Mike started his own career as a principal leading two alternative high schools serving Colorado students held in state custody or living in group homes and detention centers. Most recently, Mike was the co-founder and principal of MESA (Mapleton Expeditionary School of the Arts), a redesigned urban high school that made Colorado history by becoming the first public high school in which 100 percent of seniors were admitted to four-year colleges.
