Organizational Effectiveness + Executive Coaching
Making organizations
legible to
themselves.
Organizational effectiveness consulting and executive coaching for leaders building what matters.
Work with me
Most organizations don't fail because of bad people or bad intentions.
They fail because the operating logic, how decisions get made, how people are treated, how standards are maintained under pressure, was never made explicit. It lived in norms, assumptions, and the instincts of founding leaders. And then the organization grew.
I work with mission-driven organizations at inflection points: the moment when implicit culture stops being enough, when the gap between stated values and daily experience starts to show, when growth is creating friction no one can quite name.
I name it. I build the frameworks that close it. And I work with the people who have to live inside the system long after I'm gone.
