In 2012, Helen Crossley provided a $1 million gift to establish the Crossley Center for Public Opinion Research and promote advancement of the field. Her gift also funds Crossley Scholars fellowships to assist graduate students in pursuing careers in public opinion research.

Our Center honors the legacy of pioneer Helen and her father, Archibald Crossley, while serving our local, national and global communities as a reliable source of up-to-date political news. We have been staffed by professor and director Floyd Ciruli since 2013, a Denver-based pollster and political analyst.
