The Bexar County Constable's Office Precinct 1 is now participating in the G.R.E.A.T. Program under the direction of the U.S Department of Justice.  Bexar County Precinct 1 began this program in an effort to combat gang activity and increase "bullying” awareness. Sgt. Gabriel R. Medina, Deputy Alex Chavez and Deputy Edward Valdez are presently the only three certified instructors for 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 three deputies have successfully completed the 80 hour instructing course. In addition, they have over 460 hours of combined crime prevention instructing training, far exceeding the required standard. In addition to this, Sgt. G. Medina has several years of previous corrections 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 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.

Meet Your G.R.E.A.T Instructors

Sergeant Gabriel R. Medina

Sergeant Gabriel R. Medina joined the Bexar County Constable's Office Precinct 1 in May of 2005 with five years of previous Correctional Management Experience as a Corrections Officer, Intake Supervisor, and Classification Gang Intelligence Officer. During his time in corrections, he was selected to be part of an elite team who worked overseas on a special operation as a custody officer at Guantanamo Bay, Cuba.

Since joining Precinct 1, Sergeant Medina has served in several divisions; he has served in the Bike Patrol Unit, A.S.A.P. Unit, Civil Division, and Warrant Division. Sergeant Medina is presently assigned as the supervisor of Youth Outreach Programs, Public Relations, Pct.1 Fleet, and Court Security. In addition to this, he is a certified G.R.E.A.T. Families Lead-Facilitator, D.A.R.E. Instructor, Field Training Officer (F.T.O), and Crime Free Program Trainer.

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. 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.
