An Associate Member may be any person engaged in any type of law enforcement, including federal agents, local police officers, sheriffs’ deputies, and investigators of other entities, involved in the investigation or detection of fraud throughout the State of Colorado.

Dues are just $15 per calendar year, or $25 for two consecutive years. Dues are renewable annually (or biennially) by March 31. New members joining after October 1 of each year get free bonus time of up to three months, because their dues payments will cover them not only through the balance of the current year, but also for all of the following year.
