Dean Miller is an Admissions member at the college Haley Dunphy attended during the first few episodes of Season 4.

Dean was only seen during Haley's disciplinary hearing as admissions member after Haley was bailed out of jail for underage drinking by her father, mother and maternal uncle. He introduced Professor Williams and Aidan Feldman to Haley (Haley and Aidan actually sat next to each other in Econ.) and began the hearing telling Aidan "this is a disciplinary hearing, not JDate." and then telling Aidan to knock it off after Aidan allowed Haley's uncle, Mitchell to stay. He then asked Haley if there was anything she would like to say in her defence, to which Haley replied that she actually has no defence and started blurting out everything illegal she had done since starting college. Dean's last actions were telling Haley "we appreciate your... candor." and then asked her if there was anything else she would like to add and Haley said "Go, Wildcats?" to which Dean replied "Oh, boy." and Aidan replying "That's not even our mascot."
