I've been coaching executives for over twenty-five years. The thread through all of it is the same question: what happens when you create the right conditions for people to see clearly?

Where the coaching started

My coaching foundation is ontological. I learned the craft at Gap International, where I spent five years as Director of Strategy and Director of Product Design. Ontological coaching works at the level of how people observe the world, not just what they think about it. The premise is simple and uncomfortable: most of what we treat as fact is actually interpretation. Someone brings you tea when you asked for coffee, and in that small gap between what happened and the story you tell about it, your entire reality takes shape. Learning to notice that gap, and to hold it open long enough to choose a different response, is where transformation starts.

That training shaped everything I've done since. I went on to coach and consult to C-suite executives at companies including Genentech, Vocera Communications, and Jigsaw. I'm also trained in the Positive Intelligence methodology, the Enneagram, Circling and Authentic Relating practices, and the Upside method. Each of these gives me a different lens, but the ontological foundation is what holds them together.

A deep dive into how creative people think

Somewhere in my coaching work I became fascinated by a question: how do extremely creative people actually think? Not the mythology of creativity. The mechanics. I decided to find out, and spent the next decade in the world of mathematical problem-solving. I wrote the Numberplay column for the New York Times, bringing together world-class mathematicians and thousands of readers to work through problems in logic and creativity. I taught at Stanford, co-creating courses on intuitive reasoning with the mathematician Keith Devlin. Stanford selected me as one of twenty instructors to represent the university internationally.

What I found confirmed something the coaching had already suggested: the most creative thinkers aren't the ones who abandon structure. They're the ones who've internalized it so deeply that it becomes invisible. Their intuition comes back, but informed by discipline. That's the move that interests me, in mathematics and in life.

How this connects to forum

Forum has a methodology. There are rules: experience sharing, not advice. Confidentiality. A meeting structure refined over decades in the YPO tradition. You learn these rules. You practice them.

And then, if the group stays with it, something shifts. The structure stops being a constraint and starts being a container. The group moves together with a fluency the rules made possible but can't fully explain. Members bring things to the room they didn't plan to bring. The conversation goes somewhere nobody predicted. That's the stage of forum I work toward with every group I help build.

Mindfulness plays a role here. The ability to be present, to notice what's actually happening rather than reacting to the story about what's happening, is often what separates a good forum from a transformative one. That's the ontological training showing up in a new context.

What I do now

I run Forum Support Services, in close collaboration with Bob Halperin, the architect of the HBS alumni forum program and one of the foremost authorities on peer group methodology. Bob trains moderators and guides the program's overall direction. I focus on the West Coast: placing HBS alumni into forum groups across Northern California, Southern California, and virtually nationwide, supporting moderators through monthly meetings and ongoing coaching, leading annual retreats for YPO and HBS forum groups, and building the tools that help groups go deeper over time.

I also build with AI. Forum Sage, the AI advisor on this site, is trained in forum methodology and designed to help members and moderators think through real situations. I built it because I believe AI can be a genuinely useful thinking partner for the kind of reflective work forum asks of people, when it's designed with the right sensibility and the right constraints.

Background

Harvard Business School, MBA, Class of 1990. University of Michigan, BS in Industrial Engineering. Stanford, where I taught and conducted research on mathematical problem-solving. Five mathematical sequences I originated are listed in the Online Encyclopedia of Integer Sequences. I've spoken several times at the Gathering 4 Gardner conference, which celebrates the legacy of Martin Gardner.

In 1988 I swam the English Channel. Dover to France, eight hours and forty-six minutes.

I live in Oakland.
