Texas Gang Investigators Association

The TGIA (Texas Gang Investigators Association) is a non-profit organization that has been serving the Texas community since 1991. The Association was founded by a small group of officers charged with the investigation of street gangs, prison gangs, organized crime, and their related criminal activities.

Today, membership in the Texas Gang Investigators Association numbers over 1,490 members from across Texas and the United States.  The TGIA was formed to promote a closer working relationship among gang investigators both statewide and nationally with a view towards the rapid dissemination and exchange of information concerning gang related incidents, suspects and investigations.

The Texas Gang Investigators Association strives to provide training opportunities to its members through training seminars, quarterly newsletters, and the annual statewide training conference.


The Texas Gang Investigators Association encourages and supports legislation that would decrease or curb the occurrence of gang related crimes or to aid and assist the judiciary and related agencies in the proper adjudication of gang defendants with the stiffest penalties possible.


Additionally, the Texas Gang Investigators Association’s goal is to provide you and our communities with useful gang related information of the highest caliber.


We solicit the support of the public and non law enforcement professionals that they themselves might be better protected and educated in their awareness of and prevention of gang related crimes and activity, as well as attempt to allay any fear caused by the spread of false “urban legends”.
