The path wasn’t straight. The thread was.

I’ve worked in entertainment, as a therapist, and in venture. What I learned in one world has a habit of proving useful in another.

I’ve spent most of my career working closely with people at the top of their fields. Listening, learning how they think, and carrying their ideas through to execution.

It all comes with me.
