Christina Tziallas is a purpose-driven leader who believes that transformation begins with people. With a career spanning global roles at Kraft Heinz and Mars Wrigley, she has consistently challenged the status quo, with a proven track record of driving enterprise value, global transformation, and long-term growth.
Today, as Director of Global Growth Transformation at Kraft Heinz, Christina partners with senior leaders to embed AI-driven strategies, redesign and optimize operating models, and future-proof marketing capabilities. At the heart of her leadership is a deep belief in curiosity, creativity, and courage. Christina is known for bridging strategy and execution, inspiring teams to think differently, and shaping high-performing cultures that embrace innovation and collaboration. For her, success is not only measured by ROI but also by the growth of the people and teams around her.
Outside of work, Christina’s proudest role is being a mother to two young children and a “dog mom” to two pups. Her family is her anchor and her joy, and together they love to travel, bake, and are currently discovering the challenges (and delights) of gardening. These moments remind her that growth—whether nurturing people, ideas, or a garden—comes from patience, resilience, and care.
Christina’s journey is fueled by a passion for transformation, a love of learning, and a commitment to building futures where both businesses and people can flourish.
