G.R.E.A.T. Unit

Overview of the programGREAT: Gang Resistance Education and Training

The Bexar County Constable’s Office Precinct 1 is participating in the Gang Resistance Education And Training (G.R.E.A.T.) Program. Bexar County Precinct 1 implemented this program in 2010 an effort to help combat "gang activity" and increase "bullying awareness." Senior Sgt. Medina, Sgt. Alvarez, Sgt. Chavez, Cpl. Valdez and Deputy Sanchez are presently the only certified instructors to teach the G.R.E.A.T. Program at Precinct 1. The G.R.E.A.T. Program requires that selected Peace Officers in the United States successfully complete an 80 hour G.R.E.A.T. instructor’s course for each individual officer. All four deputies have successfully completed the requirements needed to instruct the program. In addition, they have over 520 hours of combined crime prevention instructing training, far exceeding the required standard. And, Senior Sergeant G. Medina has several years of previous correctional officer experience with two of those years being spent as a Classification Gang Intelligence Officer. These deputies bring a wealth of knowledge to the program.

The elementary curriculum Bexar County Precinct 1 teaches is delivered to fourth and fifth grade students. The elementary curriculum includes one lesson per week, for six consecutive weeks. The program requires that a certified teacher be present and help supplement classroom activities. A wide range of teaching techniques are used to include, but not limited to; questions and answers, group discussion, role-playing, and workbook exercises. Upon completion of the six week program, a graduation is held for the participating students to show a sense of accomplishment for their hard work.

Any school located in Bexar County Precinct 1 who is interested in obtaining more information about the G.R.E.A.T. Program, may contact Senior Sergeant Gabriel R. Medina at (210) 335-4593 or gmedina@bexar.org .

Medina joined the Bexar County Constable’s Office Precinct 1 in May 2005 with five years of previous Correctional Management Experience as a Corrections Officer, Intake Supervisor, and Classification Gang Intelligence Manager.

Senior Sergeant Medina is a strong believer in the philosophy by an unknown author, "Give a man a fish and you feed him for a day; teach a man to fish and you feed him for life." In other words, to understand and benefit from anything, it’s imperative that we participate in it with hands on. Senior Sergeant Medina is truly confident the G.R.E.A.T Program far exceeds this criteria to help guide our youth in the right direction and keep them away from the gang life.
