Officer of the Month


Sergeant Jacob L. Twombly Sr.’s  passion for helping people, instructing, and mentoring other officers has led him along an interesting journey in law enforcement. Jacob truly feels this profession is a calling and is thankful for the opportunity to serve.

Jacob began his law enforcement career with the Baylor Scott and White Health Care System Department of Public Safety.  Jacob was initially hired as a non-sworn Public Service Officer, but soon promoted to the position of Police Officer after attending the North Central Texas Council of Governments Regional Police Academy.  Jacob was assigned to the Patrol Division, but participated in a variety of uniformed and plainclothes special assignments.  In addition he acted as an instructor at the department and local police academies.  During his tenure at Baylor DPS, Jacob regularly encountered individuals with serious mental illness.  Jacob recognized the need for officers to receive specialized training in mental illness and worked to become a subject matter expert in the area. 

In 2014 Jacob became a Police Officer at UT Southwestern and was assigned to the patrol division.  Jacob continued to develop his expertise in mental illness education and continued to provide instruction to his fellow police officers.  Jacob assisted with the development of new policies that improved the police department’s response to mental health crisis incidents and improved the department’s relationship with mental healthcare providers.   In addition to providing instruction to police officers, Jacob began instructing medical staff in de-escalation techniques and the role of peace officer’s in the mental health arena.

Recognizing his dedication to the Mental Illness field, Jacob was named the 2017 North Texas Crisis Intervention Officer of the Year by the National Alliance on Mental Illness (NAMI).  

In 2018 Jacob was selected as the department’s Hospital Liaison officer and shortly thereafter promoted to Sergeant.   Jacob continues to teach the Mental Health Peace Officer Course, Crisis Intervention Training and De-escalation within the department and at the Dallas Police Department Academy.  

Jacob serves as a member of the Dallas County Adult Clinical Operations Team, the Dallas County Behavioral Health Leadership Team, the North Texas Behavioral Health Authority’s Planning and Network Advisory Committee, and the National Alliance on Mental Illness (NAMI).  He holds several TCOLE certifications and he has received specialized training in various areas of law enforcement.

For fun, Jacob enjoys spending quality time with his family, communicating world wide as a FCC licensed amateur radio operator (KG5UFR), and riding motorcycles.
