Who's behind this?

Hey, I'm Erin 👋

I'm a business and life strategist for agency owners and entrepreneurs, and I've been in the agency world for years as a founder of a PR + marketing agency and as the creator of Agency Owner Lab.

I've seen the full spectrum—from scrappy solo consultant figuring it out on the fly, to multi-six-figure and seven-figure agencies with real teams, real clients, and real pressure.

This guide is a collection of lessons pulled from my own experience building and running agencies, helping other PR, marketing, social, web, and creative agencies streamline, scale, and automate, and the very real mistakes I made along the way (so you don't have to repeat them).
