Students Are Saying:

“My favorite part was being challenged by the instructor as well as their sense of humor. 100% recommend this for all our supervisors.”

— Sgt. Erin Montgomery, Elk Grove PD (CA)

“Before the class I didn’t feel prepared to handle an IA but now I do. Very worthwhile training.”

— Sgt. Ryan DeJohn, Santa Barbara PD (CA)

“This course is RELEVANT. I appreciated the instructor’s style. Most POST classes are taught by an irrelevant 100-year old retiree who speaks as if he is the ultimate authority. These instructors gave options, posed questions, and said it if they didn’t know the answer.”

— Sgt. Steve Boyett, Paso Robles PD (CA)

“Excellent course and instructors. My favorite part was their energy and the info they provided.”

— Det. Vanfleet, Simi Valley PD (CA)

“I enjoyed learning about all the laws and updates. This class is 1000% worth it.”

— Investigator Patrick Weithers, City of Long Beach (CA)

“First-hand, real life experiences from the instructors made the learning environment easy to understand.”

— Sgt. RC, Santa Barbara PD (CA)
