WSI Consultant

Before founding WSI Gerstner Group, I spent over two decades leading marketing strategy for global brands at Eli Lilly—driving growth across therapeutic areas, launching high-impact campaigns, and shaping customer experience at scale. I’ve led cross-functional teams, built brand equity, and worked side-by-side with sales leaders, thought leaders, and creative agencies to solve complex business challenges.

Today, I bring that enterprise-level expertise to businesses of all sizes. As Principal and Digital Strategist at WSI Gerstner Group, I work closely with each client to build tailored strategies that generate leads, boost visibility, and drive sustainable growth. Backed by WSI’s global network, I combine deep strategic insight with proven digital execution—delivering smarter marketing that makes a measurable difference.

Let’s turn your marketing into a growth engine powered by strategy, insight, and execution.
