About

Planner at heart,
analyst by training.

I'm a performance marketer with three years of experience managing $20M+ in multi-channel media across CTV, OLV, display, audio, and programmatic. I graduated from Columbia with a B.A. in Economics, and I've applied that analytical lens to media ever since.

My work lives at the intersection of strategy and execution. I'm equally comfortable presenting optimization recommendations to C-suite clients and digging into attribution data to surface the insight that changes a budget decision.

I was selected for Universal McCann's inaugural NextGen UM global leadership cohort, and launched the agency's first global Stand Against Bland Day.

Beyond Work

A little more
about me.

🧵

Needlepoint

My analog escape. There's something meditative about turning thread into something beautiful, a good balance to a screen-heavy career.

🍞

Baking

Precision + creativity in edible form. Baking is the one place where following a process perfectly actually guarantees a great outcome.

🧘

Yoga & Pilates

Movement that requires focus, the kind that clears your head and brings you back sharper. A non-negotiable part of my week.

📚

Reading

Always have a book going. I lean toward narrative nonfiction and fiction that makes you think, the kind you're still turning over days later.

📺

Pop Culture

Genuinely passionate about what's resonating with audiences and why. It's not just entertainment; it informs how I think about media and messaging.
