More

My career spans global corporations, private equity firms, and high-growth startups—each requiring a different strategic approach, but all benefiting from my ability to accelerate growth, optimize go-to-market strategies, and execute complex deals. With expertise in enterprise services, IT consulting, and emerging technologies—including AI software, marketing technology, automation, and CX solutions—I help companies navigate transformation, enhance operational efficiency, and build high-performing sales and commercial teams. My leadership style is both strategic and pragmatic, balancing vision with execution. I’ve successfully led business units ranging from mid-market firms to Fortune 500 divisions, demonstrating adaptability across diverse business environments. I thrive in settings where agility and strategy intersect, whether that’s refining the growth trajectory of a privately held firm or steering a global business through industry disruption. Now, I’m looking to bring this experience to a small or mid-sized, fast-moving PE-backed company or portfolio — where I can lead enterprise sales, drive go-to-market transformation, and execute high-impact outsourcing and managed services growth strategies. Let’s connect if you’re building the future of technology-enabled services.
