For nearly two decades, she has helped leaders and organisations across APAC find the words that not only sound right but feel true.
Her career spans senior communications leadership roles at global brands like GIC, Salesforce, and GE Healthcare, where she worked at the intersection of strategy, storytelling, and influence.
From steering high-stakes narratives in investment management to launching region-wide thought leadership in tech and medtech, Denise has shaped messages that resonate across cultures and drive impact where it matters most.
Today, at Human & Heard, she partners with founders, executives, and changemakers to turn emotional truth into strategic narratives that inspire belief, build trust, and mobilise change. Her approach blends clarity and precision with a deep respect for the humanity at the heart of every story.
When she’s not crafting narratives, you’ll find her snowboarding in the mountains, exploring new cities with her son, or writing her upcoming children’s book series about nature and resilience.
