About

I am a wellbeing, leadership development, and culture transformation leader with deep expertise in coaching (PCC), facilitation, and designing high-impact experiences that foster trust, connection, and psychological safety. With 500+ hours of experience coaching senior leaders and teams globally, I specialize in helping organizations and individuals build the mindsets and practices that enable sustainable high performance. Currently, I serve as Senior Director of Global Employee Wellbeing and Resilience at Bain & Company, where I lead the firm’s global wellbeing strategy and drive the integration of wellbeing into Bain’s leadership, talent, and operating systems. I partner with senior leadership across regions to shape a data-driven, holistic approach to wellbeing that strengthens belonging, resilience, and the everyday Bainie experience worldwide. Over my 15+ years at Bain, I’ve moved from a decade in management consulting, advising clients across private equity, retail, and telecom, to building global initiatives that help employees align with their purpose, grow in self-awareness, and thrive. My mission is to enable leaders, employees and organizations to create meaningful, lasting impact through a wellbeing culture and sustainable performance.
