Building high-growth marketing systems that fuel scale, unlock operational efficiency, and drive business momentum
I’ve led marketing at health tech and DTC companies where the line between performance and product is thin—and results matter fast. I work best when I’m not just optimizing campaigns but helping shape the bigger picture: how a business grows, how customers experience it, and where the next inflection point might be hiding.
My experience includes managing seven-figure budgets, building marketing teams from scratch, and working directly with product, ops, and CX to move the business forward. While my background is in digital marketing, my interest has always been broader: how systems scale, how teams align, and how good businesses get better.
