Katherine (Winter) Sellery

Katherine Winter Sellery is a leadership communication expert, three-time TEDx speaker, and CEO and founder of BalanceWork-Life, where she helps executives and organizations transform how they communicate under pressure. Sellery’s work focuses on one of the most overlooked drivers of performance: how leaders navigate difficult conversations. From executive teams to high-performance organizations, she equips leaders with practical tools to reduce defensiveness, resolve conflict and create alignment so decisions move faster, trust strengthens and teams perform at a higher level.

With a background in mediation, law and international business, Sellery brings a unique depth to leadership development. She spent more than 30 years as a commodities trader based in Hong Kong, operating in high-stakes, high-pressure environments where communication directly impacted outcomes. That experience now informs her work with leaders navigating complexity, competing priorities and interpersonal dynamics at scale.

Sellery’s approach integrates conflict resolution, emotional intelligence and communication strategy into a clear, actionable framework that leaders can apply immediately. Her work has supported thousands of leaders, educators and professionals globally, helping them shift from reactive communication to intentional, results-driven leadership.

A three-time TEDx speaker and bestselling author, Sellery has been featured across major media platforms and international stages, including Advertising Week New York and the International Women’s Conference. She has shared stages with global thought leaders and addressed audiences ranging from executive teams to large-scale international events.

Through her keynotes and leadership trainings, Sellery helps organizations strengthen communication as a core performance capability because how leaders communicate under pressure shapes culture, execution and results. Communication under pressure is not a soft skill; it is performance infrastructure.
