Sonya Lee

I’m a senior marketing professional with 4+ years developing and executing integrated marketing strategies within EY’s large, matrixed global organization. I own marketing plans end-to-end—from brief development and seasonal planning through cross-functional execution, budget management, and performance reporting. I bring a data-informed approach and a consistent track record of on-time, on-budget delivery across multiple channels.

I’ve developed and owned integrated marketing plans for EY Korea’s service lines, coordinating execution across content, digital, paid media, PR, and events to deliver initiatives on-brand and within budget. I authored marketing briefs and led partners through the full campaign lifecycle, acting as the central coordination point for messaging consistency, quality standards, and milestone delivery. In practice, my multi-channel work drove a 25% increase in website traffic over three months, delivered LinkedIn ad campaigns with a 20% uplift in conversion rates, and supported high-visibility DOOH at Incheon International Airport reaching ~450K travellers monthly.

I operate with the same “global–local” dynamic required for Canada–US integration, translating global brand direction into locally resonant campaigns while maintaining HQ alignment. I champion brand stewardship across owned-channel touchpoints (EY.com, LinkedIn, KakaoTalk), developing market-specific content grounded in local audience insight while staying aligned with global brand standards. I also managed campaign and event budgets up to CAD ~$50K per cycle and owned end-to-end delivery for large-scale seminars, plus led cross-functional platform transitions, including an 18-month AEM migration with zero service interruption.

Leadership is a core part of how I work: I directed and mentored 20+ interns and junior marketing staff, guiding them through campaign execution, content development, and professional growth. I expanded my scope into corporate PR, tripling YoY activity volume and driving 123% growth in media coverage by coordinating English-language press releases with global teams. I also built contributed article programmes with top business publications to sustain thought leadership and support 15+ expert spokesperson appearances per month.
