WhoFest
WhoFest is a recurring Doctor Who-focused science fiction convention held in the Dallas, Texas, area. First held in November 2013 as a one-off celebration of the 50th anniversary of Doctor Who, WhoFest is now held annually each April.
WhoFest is a production of the Dallas Future Society, a non-profit 501(c)(3) corporation that seeks to promote the advancement of science, literature, and music for all mankind. This is the same organization that has run FenCon, a literary and music oriented general interest science fiction convention, since 2004.
