About

I'm a B2B digital marketing leader with 15+ years in demand generation, paid digital, and full-funnel growth across SaaS, cybersecurity, martech, and fintech. I've built and run programs spanning search, display, CTV, social — LinkedIn, Reddit, Quora — retargeting, and third-party media at global scale, while staying close to the data and the team doing the work.

I'm as comfortable setting strategy as I am rolling up my sleeves on execution. What I'm known for: strong cross-functional relationships, consistent delivery against pipeline goals, and being the person managers bring with them when they move on.
