Instructors

MAJ (RET) Joe Pimentel

I am the Senior Army Instructor (SAI) of the Junior Reserve Officers Training Program (JROTC) at G.B. Trimble Tech H.S. I joined the Bulldog team in 2015 and I am the primary instructor for the seniors in JROTC. I coach the Robotics Team, Raider Team, Male Color Guard, and the Armed Drill Team. 

I retired from the U.S. Army after 26 years of active duty service while serving in numerous leadership positions in various locations across the country, as well as overseas. My primary focus is to coach, teach, and mentor seniors to create their goals and develop a plan for their post high school journey while building their communication, teamwork, and confidence skills. 

I received my BA in Organizational Leadership from Chapman University and an MA in Leadership & Management from Webster University. 

SGM (RET) Roel Cortes

I am an Army Instructor (AI) at the JROTC (Junior Reserve Officer Training Corps) program at G.B. Trimble Tech HS. I have been a member of Bulldog Battalion since 2018, and I am the primary instructor for the Sophomores and Juniors. I am the coach for Female Color Team, the Unarmed Drill Team and the JROTC Leadership & Academic Bowl Team (JLAB).

 Prior to coming to Trimble Tech HS, I was a JROTC Army Instructor (AI) in a Dallas school for 5 years. I retired from the U.S. Army after serving 25 years in positions in the U.S. and overseas. My goal for the cadets is to expand their minds, develop leadership skills, and prepare them to become productive citizens.

 I received my B.S. in Geology from Texas A&I University, and I attended the United States Army Sergeant Majors Academy.
