About
As Executive Vice President and Chairperson of North America at OPmobility, I lead a talented and passionate team across all our business groups, driving strategic growth in a region that contributes ~30% of our annual global revenue. Our focus is on accelerating both organic and transformative growth while expanding our market share and deepening our presence across the mobility sector. I foster a positive, growth oriented environment where talent is developed, ideas are shared, and bold visions are realized. Prior to OPmobility, I served as Managing Director of GM Canada, where I led the organization to regain the #1 market share position after more than a decade and delivered record profitability and EBIT margins. These milestones reflect my ability to lead through disruptive change, define bold strategies, and execute with precision. I am an authentic, collaborative leader driven by curiosity and a passion for innovation. With a strong engineering foundation and extensive experience across product development, operations, sales, and marketing, I bring a disciplined, results-oriented approach to every challenge. I’ve successfully led product launches that exceeded targeted EBIT by over 50%, demonstrating my ability to deliver exceptional value and performance. I thrive in environments of innovation and transformation, and I’m committed to building high-performing, growth-oriented teams. I believe in the power of relationships, open communication, and a culture that celebrates wins while staying humble and hungry.
