Reneé Hall served as Chief of the Dallas Police Department from 2017 to 2020, the first woman ever to lead the organization. Previously, Hall served in the Detroit Police Department for many years, eventually becoming Deputy Chief in 2014. Hall made the move to Dallas in 2017.

Hall was born in Detroit into a policing family. She earned a Bachelor of Science degree in Criminal Justice from Grambling State University, as well as two Masters of Science degrees from the University of Detroit Mercy in Security Administration and Intelligence Analysis respectively.

In Hall’s years as Police Chief, Dallas saw a 5.7 percent reduction in overall crime in 2017 and a 5.97 percent reduction in violent crime in 2018. The department implemented new technologies such as the Dallas On-Line Reporting System (DORS) and Text to 911.  Hall also oversaw the department's launch of the Starlight program, a 6-month proof of concept that allows officers to use state-of-the-art cameras and lighting to capture crime in real time. Hall ultimately led the way to the department’s launch of a Real Time Crime Center.  Additionally, the iWatchDallas App, a tip application that allows users to submit information to law enforcement, was relaunched.  

Hall also made officer welfare a priority, working with city leaders to increase the starting salary of officers, restructure the civil service exam and conduct on-site recruiting and testing in cities like New York and Chicago. These efforts led to the Dallas Police Department accepting the largest academy class in its history. Hall also oversaw the building of a new gym at police headquarters.

In accordance with her philosophy of 21st Century Policing, Chief Hall prioritized community engagement and outreach by regularly connecting with officers in the field, as well as meeting with Dallas community groups, professional leaders, and local organizations. Chief Hall spearheaded the City of Dallas' restructuring of the Community Police Oversight Board, as well as the police department's first Youth Summer Jobs program, that allowed business leaders and community stakeholders to mentor at-risk youth through workforce development.

Hall is a proud member of Delta Sigma Theta Sorority, Incorporated, The International Women's Forum (IWF), Major Cities Chiefs Association (MCCA), National Organization of Black Law Enforcement Executives (NOBLE), International Association of Chiefs of Police (IACP) and the Police Executive Research Forum (PERF).  She has also completed training at the FBI National Academy and the Major Cities Chiefs Executive Leadership Institute (PELI IV).
