About

Dedicated security professional (SME: National Security, Personnel Security, Investigations & Adjudications) 10+ years of leadership experience | TS/SCI

I don't just conduct investigations; I uncover the truth.

I don't just manage risk; I protect the integrity of the mission.

I don't just identify problems; I neutralize them.

From law enforcement agencies to the White House, I have advised and mitigated risk for senior leaders at the highest levels of power. When something is not working, I am who you call.

Here’s what I know: You have goals. You have challenges. You have a vision that requires a leader who doesn't blink. You want to reach peak efficiency and productivity, why not engage with someone already at the summit that can walk you backward through the steps it takes to get there?

If the pressure is on, the stakes are at their highest, and the margin for error is zero, I’m the person you want in the room.

As I transition into my next chapter, I am looking for my new mission. If you need a strategist, a leader, or a SME who knows how to navigate some of the most complex environments on earth, we should talk.
