About Madison Investigative Services

A legacy of dedication and precision

Founded in 2011, Madison Investigative Services was built on a simple premise: bring real law enforcement expertise — not just a license — to every case we take on.

Our Story

Investigators first, consultants second

At Madison, professional investigative services are at the heart of what we do. Backed by more than 35 years of hands-on law enforcement, investigative, and public safety experience, Madison Investigative Services provides thorough, professional investigations grounded in integrity, precision, and results.

That experience shapes how we approach every case: methodical, discreet, and thorough, whether assisting a family in crisis, a business facing a workplace complaint, or an attorney building a case. Over the years, Madison has completed hundreds of investigations involving complex and sensitive matters, with investigative findings presented and defended through courtroom testimony and state registry hearings. That same depth of investigative experience extends to major and high-profile cases, including cold-case work by our founder, Don DiStefano, whose investigative expertise has been featured in true-crime docuseries produced by Netflix and HBO, as well as in a major feature film from Sony Pictures.
