The Work

You’re facing a decision that keeps circling your mind. The stakes are high. The variables are complex. And you need a confidential sounding board who sees what others miss.

I help you understand how perception — conscious and unconscious — is shaping your situation before you make your move.

Through our private conversations, we uncover the beliefs, biases, and invisible dynamics at play in your negotiations, conflicts, leadership challenges, and critical decisions. You’ll make the final call. I’ll ensure you have every piece of information — favorable, unfavorable, or uncomfortable — before you do.

Why Clients Call Me Their “Fiercest Ally”

I read what’s unspoken. Expert in body language, subtext, and the dynamics beneath the surface of every interaction.

I ask the questions that need answers. Unafraid to tactfully address the elephant in the room — the issues everyone senses but no one names.

I operate in high-pressure environments. Shareholder activism, regulatory scrutiny (SEC, FDA, FTC), media crises, internal conflicts, M&A negotiations — I’ve navigated them all.

Everything is confidential. NDAs signed. Nothing shared. Your privacy is non-negotiable.

How We Work Together

Every engagement is tailored. Depending on what you need:

• Private advisory sessions — One-on-one strategic counsel for personal or professional challenges
• Perception audits — “Fly on the wall” analysis of your meetings, teams, or communications
• High-stakes preparation — Before negotiations, board meetings, media appearances, or difficult conversations
• Team dynamics work — Breaking through barriers when communication breaks down

Plus: If I know someone who can help you achieve your objective, I’ll tell you — and make the introduction.

Who I’ve Worked With…

• C-suite executives managing crises, transitions, and reputation challenges
• Managing Directors at VCs and Investment Bankers seeking a sounding board and thought partner
• Founders navigating growth, conflict, or exits
• Individuals facing career-defining decisions or personal crossroads
• Companies addressing regulatory scrutiny, shareholder activism, or organizational change
• Lawyers and Legal teams

Background: I founded and sold two communications companies. Counseled hundreds of clients since 1993. Participated in 10,000+ investor meetings. Developed the Perception Dynamics™ framework — a philosophical approach to understanding how perception drives every outcome. Full bio here.

If You’re Ready…

If you suspect you or your team could be operating at a higher level — or if there’s a decision that won’t leave your mind and you need a safe place to unpack it — this is your invitation.

Schedule a complimentary, confidential consultation. Tell me what you think the issue is. I’ll tell you if and how I can help — or connect you with someone who can. NDA’s signed.

Every conversation is beneficial, whether we work together or not. That’s my guarantee
