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
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.
