We caught up with the brilliant and insightful Deborah Colleen Rose a few weeks ago and have shared our conversation below.

Deborah Colleen, looking forward to hearing all of your stories today. What’s the best advice you ever gave to a client? How did they benefit / what was the result?

The best advice I’ve given a client is simple, but it changes everything: slow down and write it all out before you ever sit down with an attorney or investigator. I had a client who came in overwhelmed, jumping from detail to detail, missing key pieces without even realizing it. I told them to go home and document everything they could remember, timelines, names, conversations, small moments that didn’t seem important. When they came back, the story had shape. Gaps were clear, contradictions stood out, and the emotional fog had lifted just enough for us to see facts instead of chaos. That written record became the backbone of the case. It saved time, reduced legal costs, and gave their attorney something solid to work with instead of fragments. More than that, it gave the client control. When you put it on paper, you stop reacting and start thinking. That shift alone can change the outcome.

Awesome – so before we get into the rest of our questions, can you briefly introduce yourself to our readers.

I didn’t come into this field through a classroom. I came up through the trenches. I started out owning a bail company, and if you know that world, you know it teaches you fast. I did my own skip tracing and bounty hunting, knocking on doors, reading people, following threads that didn’t want to be followed. That work built my instincts. It taught me how to see what’s missing, not just what’s in front of me. From there, moving into private investigations wasn’t a leap, it was the natural next step.

For over 35 years, ISGU has served clients who need answers that actually hold up under pressure. Under my leadership, we’ve worked with individuals and corporations on everything from civil and criminal cases to divorce, due diligence, corporate mergers, hostile takeovers, employee terminations, background checks, and surveillance. That’s a wide net, but the common thread is this: people come to us when the stakes are high and the truth is buried.

Here’s where I differ from a lot of firms. Many investigators hand you a stack of data and call it a day. That’s not enough. Data without interpretation is like handing someone puzzle pieces without the picture on the box. I focus on what the information means, how it connects, and how it can be used. I don’t just gather facts, I build a narrative that stands up in real-world situations, whether that’s a courtroom, a negotiation table, or a corporate boardroom.

What I’m most proud of isn’t just longevity, though 35 years says something. It’s the trust. Clients come back. Attorneys rely on us. Businesses call when something doesn’t sit right and they need clarity, not guesses. I’ve built a reputation for being thorough, direct, and hard to shake when I’m on a case.

If there’s one thing I want people to understand about me and my work, it’s this: I don’t chase noise. I go after what’s real. I ask better questions, I look where others don’t, and I stay with it until the story makes sense. In this line of work, truth has a way of hiding in plain sight. My job is to bring it into the light and make it usable.

Can you share a story from your journey that illustrates your resilience?

I built my career by adapting to what the work demanded, not what was comfortable. I started in criminal defense investigations, where the pace is fast and the margin for error is thin. You learn quickly that facts alone aren’t enough, you have to find them under pressure and make them usable. From there, I moved into workers’ compensation cases, which required a different kind of discipline, patience, documentation, and the ability to spot inconsistencies over time. As my work expanded, I transitioned into corporate investigations, handling fraud, due diligence, and complex background checks where the stakes are often financial, reputational, and long-term.

Each shift wasn’t a restart. It was a refinement. I carried forward what worked and sharpened what didn’t. Over time, one skill set began to define my work: my ability to get people to talk when they’ve already said no. Witnesses who refused attorneys, ignored calls, or shut down under pressure would often open up in my presence. That doesn’t happen by accident. It comes from reading people, building trust quickly, and knowing when to push and when to stay quiet.

That ability has become the backbone of my litigation support work. When others hit a wall, I find a door. When information seems out of reach, I find a way to bring it forward in a form that actually helps the case. My resilience isn’t just about staying in the game, it’s about evolving within it and becoming more effective at every stage.

How’d you build such a strong reputation within your market?

My reputation was built on two things most people say they value but don’t always deliver, clarity and competence. I don’t sugarcoat. Clients don’t come to me for comfort, they come for the truth, even when it’s inconvenient. That kind of directness builds trust over time because people know I won’t waste their time or lead them down a dead-end path.

But honesty alone isn’t enough. I made it a point to become deeply skilled in my field. I didn’t just work cases, I studied patterns, refined my methods, and stayed sharp as the industry evolved. That commitment positioned me as more than a service provider. It made me a resource.

Over time, that grew into training other investigators and offering continuing education credits. When your peers trust you to teach them, that says something. It means your work holds up under scrutiny, not just with clients, but within the profession itself.

So my reputation didn’t come from marketing. It came from consistency. Telling the truth, doing the work right, and raising the standard, not just for myself, but for others in the field.
