Frank Bijdendijk (Rotterdam, 1944) has studied Architecture in the city of Delft. When he finishes his studies, and military service, he starts his career at construction company Bredero. After leading a project in the Utrecht district Lunetten, Bijdendijk becomes director of housing corporation Het Oosten in Amsterdam. In 1998, he manages to build a bridge between the Turkish organisation Milli Görüş, and the district council of De Baarsjes. When the idea for the Westermoskee arises, Het Oosten steps in as a third project partner. Years later, in 2006, Bijdendijk and his colleagues would get into a conflict with the new mosque administration.
