Connecting people, ideas, and growth
The short version
How I work
I'm a connector who gets things done with warmth and rigor — the person people rely on when ambiguity needs someone to ask the question that unlocks insights. I started in newsrooms, learning to find the story inside the noise, then moved into finance at Fidelity, where that instinct became strategy, data, and enterprise decision-making.
Today, I sit at the intersection of both. I build the structure that moves ambiguous, high-stakes work forward, and I tell the story that gets leadership aligned.
