Introducing Darrin Greeley, the CEO

Darrin Greeley is the CEO of Greeley & Associates and brings more than 35 years of law enforcement experience across a wide range of senior command positions. Alongside a team of seasoned associates drawn from law enforcement agencies throughout Massachusetts, he provides the leadership and direction that define the firm’s consulting approach.

Command & Investigative Experience

Darrin retired in May 2022 as a captain in the Boston Police Department.

This depth of investigative and command experience directly informs the firm’s consulting services, ensuring that recommendations are grounded in real-world application—not theory.
