The Department of Public Safety (DOS) unifies all the city agencies tasked with ensuring Denver is the safest and most welcoming city in the nation. Our mission is to deliver a full spectrum of high-quality public safety services to individuals who live, work and visit the City and County of Denver.

Under the guidance of the Executive Director, who is appointed by the city's mayor, DOS provides management, discipline, human resources, administrative support and policy direction for Police, Fire and Sheriff Departments,  the 9-1-1 Combined Communications Center, Public Safety Youth Programs, Community Corrections and the Gang Reduction Initiative (GRID). The DOS also oversees the Public Safety Cadet Program, a program for high-performing high school graduates who are interested in becoming a police officer, firefighter or deputy sheriff in Denver.

The Executive Director is the highest authority in the Department of Public Safety and provides oversight, leadership and guidance to the each of the divisions through their leadership teams. In addition, the Executive Director's office is responsible for issuing fair and unbaised discipline decisions on behalf of Police, Fire and Sheriff Departments. 


Public Safety Leadership Team

Troy Riggs joined the Department of Public Safety in November 2017, bringing 30 years of experience and a national reputation for excellence and innovation in public safety.

During his career, Executive Director Riggs has developed data-based practices to address the degradation of residents’ quality of life, expanded community-government engagement, assisted with the successful merger of government services, and established operational efficiencies while increasing productivity. 

He has held the positions of Police Chief and Director of Public Safety in Indianapolis, Indiana, and the positions of Police Chief and Assistant City Manager in Corpus Christi, Texas. He also served as a police officer for 20 years, working his way from recruit to Assistant Chief and Chief of Staff during that time.

Most recently, Executive Director Riggs served as the Vice-President of Sagamore Institute where he oversaw day-to-day operations and advanced strategies to support innovations in criminal justice.    

His experience in public service is further complemented by his commitment to community engagement. He has received many leadership and community awards, including recognition by the National Association of the Advancement of Colored People and the League of United Latin American Citizens.

Executive Director Riggs is a Political Science graduate of the University of Louisville in Louisville, Kentucky and he holds an EMBA from Sullivan University in Louisville, Kentucky. He and his wife Kara have been married for over 25 years and have two sons, David and Caleb. 

Mary Dulacki is the Deputy Director responsible for discipline of the Denver Police and Denver Fire departments. In her role, assumed in April 2019, she reviews internal investigations, oversees disciplinary proceedings and other administrative matters.

Ms. Dulacki, a native of Denver, is a former prosecutor and judge. During her 11 years working for Department of Public Safety, she established herself as a leading expert in the Colorado Open Records (CORA) and Colorado Criminal Justice Records (CCJRA) acts. She also drafted policies to support reform efforts in the Denver Sheriff Department. And, she brought city and state agencies and stakeholders together to address arrest-identification issues and advised on policy matters as a member of the city’s Information Governance and XO committees.

Her responsibilities as deputy director who oversees discipline requires her to possess in-depth knowledge of the law along with department rules and policies. Ms. Dulacki says that her predecessors worked hard to establish clear disciplinary matrices that identify and communicate what is expected of employees, who often face difficult split-second decisions. Thorough training, education and respectful dialogue are essential for the best outcomes.

Ms. Dulacki also will prepare and present public reports on the use of force, disciplinary actions and training supporting the department's goals of accountability and transparency to the Denver community.

Ms. Dulacki is a graduate of the University of Colorado at Boulder and the University of Denver Law School.


Laura Wachter joined Department of Public Safety in November 2011 as Deputy Director of Administration. Since that time, Wachter has provided policy oversight and strategic planning for 911 Communications, Community Corrections, Youth Programs and Human Resources. 

In addition, she has established department-wide efficiency, saving and performance metrics; helped develop a department-wide strategic plan; and collaborated with the Police and Sheriff Departments to implement Peak Performance and their strategic resource alignment projects.

Wachter began her career as a budget analyst with the City of Kansas City, Missouri and then moved to Phoenix, Arizona to become the Financial Manager for the State of Arizona School Facilities board in 2002, where she successfully prepared an annual $918.8 million budget request for the Governor, and created a 5-year strategic plan that incorporated revenue models, expenditure trend forecasts, and performance measures.

In 2004, Wachter was hired by the City of Phoenix to coordinate a $4.9 billion 5-year capital improvement plan. After the plan was successfully implemented, she joined Denver’s Budget Management Office at the end of 2004 as a Senior Financial Management Analyst.

Over the next six years, Wachter became an indispensable part of the Budget Management Office, and an essential departmental liaison to the Department of Safety. She was promoted to Budget and Management Supervisor in 2007 and served as Manager of Budget Operations from 2009-2011.

Wachter has served on numerous boards and task forces, including the Denver Asset Building Coalition and Property Confiscation Board. She has also been a Collective Bargaining team member since she joined the City of Denver in 2004.

Four years later, she earned a Master of Science in Public Policy and Management, with Distinction, from Carnegie Mellon University, Pittsburgh, Pennsylvania. Wachter and her husband, Mark, have two children, Zach and Quinn.

Eric Williams joined the Department of Public Safety in June 2018. He returned home to Denver from the Federal Bureau of Investigation (FBI) in Washington, D.C., where he served as an advisor to FBI directors James B. Comey and Christopher A. Wray, as well as Bureau executive management.

In the Deputy Director role, Williams will continue the Department’s critical work to strengthen the public’s confidence and trust in Denver’s safety agencies. He will focus on fortifying important relationships with the community and other stakeholders to improve processes and, in turn, safety throughout Denver.

Williams will also advance initiatives, goals and objectives for the Department which foster innovation and a culture of inclusivity, accountability, and ethical behavior. As a vital resource to safety staff, he will work closely with executive leadership to ensure that both public input and mayoral objectives are successfully implemented. He will also focus on coordinated activities between first responders across Denver’s emergency response system to promote collaboration and efficient operations.

Prior to returning to Denver, Williams served as a Supervisory Special Agent with the FBI, where he advised international law enforcement partners on significant investigations concerning the United States and West African countries. Prior to this assignment, he spent over a decade in various roles at the FBI. From managing the FBI’s relationships with many of its oversight committees in the U.S. Congress as the Unit Chief in the Office of Congressional Affairs (OCA) to leading high-priority criminal and national security investigations, Williams has been instrumental in protecting our country at one of the top federal law enforcement agencies in the United States.

While in the OCA, Williams was detailed to the U.S. House Judiciary Committee as Counsel, where he advised Members of Congress on effective methods to combat public corruption, terrorism, and color of law violations. Additionally, he worked with staff to advance legislation concerning criminal justice reform, international data sharing, and the provision of protective gear for first responders.

Williams is a Colorado native who grew up in the Denver metro area. He is a licensed attorney and U.S. Navy veteran who earned a Juris Doctor degree from the University of Colorado, School of Law, Boulder, and a Bachelor of Science degree in Criminology and Political Science from Metropolitan State University of Denver.
