As we continue to face the unpredictable security threats created by domestic urban unease and international terrorists, businesses must continue to update their safety practices to protect their customers, personnel and business interests. McCarthy Byrnes works to ensure our clients have a strong line of defense on every front.

Here are some questions that many corporate officers ask and that McCarthy Byrnes can answer:

  • Should my company outsource or in-source security operations?
  • Do we need a Security Director or Chief Security officer?
  • Is our corporate approach to security using today’s best practices?
  • What are our short-term and long-term strategies for ensuring the safety of our employees and our offices?
  • What is our corporate liability if something goes wrong?


We will work with your executive leadership team to safeguard your corporation. We apply proven policing techniques in assessing what your company can do immediately to protect lives and assets from external and internal threats. Ultimately, we can help your company design or enhance an approach to security that aligns with your mission and corporate culture.

McCarthy Byrnes draws on years of executive command and operational experience in fighting crime and terrorism. We will assess your organizational security structure in two ways: a first responder perspective and a crime prevention perspective.

For instance, we will assess your company’s emergency response planning in accordance with the current practices used by top law enforcement agencies. This includes reviewing current operations, use of technology and human resources in order to achieve the best possible outcomes in an emergency situation.

Our crime prevention strategies assessment includes analyzing the geographic location(s) of your company and conducting a thorough review of the immediate external threats like current crime patterns in the area. Internal threats like employee theft will also be assessed. We will work to ensure your company’s well-being inside and out.

From educational institutions to tourist destinations, organizations in today’s reality must guard against becoming a high-value target in the mind of a criminal or fanatics. Companies that reside in high-value target properties must take additional precautions to assess and understand how to best safeguard their customers, employees, and business.

Throughout his extensive law enforcement career, Garry McCarthy, president and CEO of McCarthy Byrnes, has consistently delivered superior results. Through executive leadership roles, operations management techniques and implementing innovative crime control strategies, McCarthy has significantly reduced crime and streamlined efficiencies.

From 2011 to 2015, Mr. McCarthy served as the Police Superintendent for the City of Chicago—the second largest police department in the nation. He oversaw a $1.4 billion budget and 13 thousand sworn and civilian employees. During his tenure, he worked diligently to reduce violence and crime by using proven crime fighting and prevention strategies that helped reduce crime in other major American cities including New York City and Newark. Under Garry McCarthy’s leadership, Chicago saw four straight years of reduction in overall crime and the fewest violent crime incidents since the 1960s. Through policy and training efforts, he reduced police related shootings by 70 percent and police complaints by 50 percent. Since 2011- 2015, overall crime in Chicago fell by more than 37 percent—across the FBI’s combined major crime indices.

Prior to his role as the Superintendent of the Chicago Police Department, McCarthy served as the Police Director for Newark, New Jersey from 2006 to 2011. Under his watch, the department led the nation in murder reduction in 2008. From 2006 to 2008, he oversaw a 12 percent reduction in overall crime and reduced civilian complaints against personnel by more than 20 percent. He has also created innovative systems that helped ensure accountability throughout the police force. This role presented a mix of challenges. Due to state-mandated layoffs, McCarthy was called to implement strategies that streamlined the department and reduced the budget by more than $33 million. Here, he removed non-essential roles and ensured that there was no disruption in patrol levels or officers on the street.

McCarthy began his law enforcement career with the New York City Police Department, NYPD. Over the course of his career with the NYPD, he held multiple supervisory and command positions including Deputy Commissioner of Operations. In this role, he acted as the principal crime control strategist for the department. He was also a key policy maker responsible for directing the planning and motivating a staff of thousands. He was critically involved in planning, coordinating and directing the response to the World Trade Center attack and aftermath. After his involvement, he was called to act as the Coordinator of the Metropolitan Committee on Counter Terrorism, a committee comprised of 43 federal, state and local agencies.

Mr. McCarthy has been awarded more than twenty Commendations for Valor, is a sought after expert and international public speaker and is an active member of many organizations. He served as the first vice president of the Major Cities Chiefs Association and is a member of the Police Executive Research Forum. He was also featured in the award-winning documentary Brick City. McCarthy attended the prestigious Police Management Institute at Columbia University as well as the graduate program at Marist College in New York. He holds a Bachelor of Arts from State University of New York-Albany and currently resides in Chicago, Illinois with his wife, Kristin.

Partner & COO - McCarthy Byrnes

As an accomplished law enforcement officer with close to three decades of dedicated service, Robert Byrnes has distinguished himself in a variety of roles throughout his career which eventually led him to establish Strategic Security Solutions, Inc., a private investigative agency providing comprehensive security services since 2004.

In the span of his law enforcement career, Robert has been involved in a wide range of criminal investigations, many of which involved dangerous undercover work. Through his tireless efforts, he was able to maintain a 98% conviction rate, helping to stem the tide of gang violence and drug trafficking in the greater Chicagoland area.

After joining the South Chicago Heights Police Department in 1994, Robert rose rapidly through the ranks with hard work and perseverance. By 2002, Robert’s work in law enforcement was recognized as exceptional by the Illinois Secretary of State, and he was appointed as Deputy Director for the Secretary of State Police Department. Robert was directly responsible for managing the Special Operations Support Division’s resources, including SWAT teams, underwater dive investigations, and the Hazardous Devices Unit. In addition to these duties, Robert oversaw motor vehicle licensing and regulation, identity theft investigations, and
security at Secretary of State facilities, as well as the Capitol Complex.

Robert also served as a respected member of the Cook County Sheriff’s Police Narcotic High Intensity Drug Trafficking Area Task Force (HIDTA) for over 20 years. As a member of this elite unit, Robert led numerous state and federal criminal cases against violent and repeat offenders. From case building to trial testimony, Robert established himself as an outstanding investigator and expert witness.

As a member of the International Law Enforcement Educators and Trainers Association, Robert received annual training on criminal trends and investigations. He attended both the Northwestern University School of Police Staff and Command as well as the Executive Police Management Program. Additionally, he has been certified by the Illinois Training and Standards Board as a gang specialist and investigative training instructor. In his role as an educator, Robert has provided invaluable insight into criminal investigations for hundreds of
police officers from different agencies throughout the State of Illinois.

For nearly two decades, Robert has served as a security consultant and provided private investigative services through Strategic Security Solutions, Inc. for business owners and government agencies. Robert has also furnished discrete and vital assistance to many individuals and families seeking remedies and solutions for private matters.

Robert is now joining forces with Garry McCarthy, the former Superintendent of the Chicago Police Department, to establish McCarthy Byrnes, a private security consulting firm. Both gentlemen possess decades of knowledge and experience to mitigate threats and lessen liabilities in a world wrought with costly litigation and active threats.
