AB​OUT DIA

In 1966, Investigators from various California Public Defender offices created the Defense Investigators Association(DIA). Today, the DIA serves Public Defender Investigators as active members and other criminal defense professionals as associate members. The association continues to provide professional training through annual seminars and a fully accredited training academy (DITA). In addition, the association provides networking opportunities for its members
