Answer: Denise Dowse
Dowse, born in 1958 in Honolulu, Hawaii, portrayed Principal Garrison. Garrison was the Principal of Richmond High School and managed the school's finances. Garrison remarked to Coach Carter that she admired his methods of getting his players to do well but felt they were extreme. Garrison noted to Coach Carter that Richmond High School was ranked low on the Academic Performance Index and, thus, the school did not get rewarded by the State of California for good school performance. Due to this, she told him she had less money to pay faculty and staff and that Carter would be lucky to graduate even one of the five seniors on his team. At the meeting to determine if the lockout on the gym should end, Garrison voted to not end the lockout. Dowse guest starred on the TV series "Gilmore Girls", "Law & Order", and "Everwood."
