SEVENTY-
THREE

HOME

 

Strategic presence for complex or sensitive situations.

 

I work with principals and families navigating transition, friction or quiet exposure.

 

I bring structure where there's chaos.
I bring clarity where there's fog.
Calm where discretion matters most.

ABOUT - Who I Am

 

I've spent 30 years operating in environments that reward precision and trust.
 

My background runs through military SIGINT, international structuring, operational leadership and family office governance. Different worlds. Same discipline underneath: read the whole picture before you act on any part of it.
 

Most advisors go deep in one lane. I go wide across all of them, and stay independent of every one.


I don't chase visibility. Being grey in a colorful world is how I work. 

SERVICES - What I Handle

 

  • Diagnostic review across governance, structure and exposure.
  • Fractional Chief of Staff to the principal, coordinating legal, financial and family advisors.

  • Principal protection: reputational, informational and structural.

  • Long-term advisory retainer for principals who need one point of continuity.

 

I step in where the stakes are high and the picture is scattered across too many people who each hold one piece of it.

CONTACT - Reach Out Quietly


I don't advertise. I work by verified introduction only.

 

Inquiries are screened upon receipt. Response depends on fit, not urgency.

 

Engagements run as a Diagnostic, a fixed-term Build, or an ongoing Anchor retainer, depending on what the situation calls for.
