Home base

My work has never fit neatly into one box.

I've spent my career at the intersection of people, business and growth. I've built HR functions from the ground up. Advised founders and executives. Helped companies navigate funding rounds and acquisitions. Built People Operations infrastructure for rapidly scaling organizations.

And then I took those same skills beyond the walls of a company — leading an organization focused on economic development, workforce opportunity and the future of one of Atlanta's most important neighborhoods.

Different environments. Same work.

What's next

I'm always interested in the right problem.

Executive leadership. Advisory work. Boards. Companies navigating real growth or change.

If the mandate is to build stronger teams, better systems and an organization capable of what's next, I'm interested in the conversation.

Let's build something better.
