What I'm looking for

I seek a senior marketing or account leadership role where I can drive integrated campaigns, collaborate with cross-functional teams, and deliver measurable ROI while mentoring teams and growing brand visibility.

I am a marketing management and client services professional with extensive experience leading integrated digital, social, video, and omnichannel campaigns across Canada and Europe. I have led national multi-channel programs, managed brand portfolios, and partnered with senior stakeholders to translate business objectives into production-ready briefs and measurable marketing outcomes.

I deliver data-informed campaigns and act as a brand steward, having driven measurable results such as a 40% sales increase for Jägermeister in 2017 and managing high-profile accounts across financial services, real estate, consumer brands, and spirits. I thrive in agency and client-side environments, managing budgets, timelines, and cross-functional teams to achieve strategic priorities and strong ROI.
