Empowering transformation in the age of AI
Trusted by Leaders
Proven Results
I am a transformation strategist who prides himself on turning complexity into clarity and disruption into growth. Having worked half my career as a management consultant, including almost a decade in Big 4, served as an executive at Fortune 500 companies and led mission-driven nonprofits, I have led high-stakes integrations, restructurings, and billion-dollar pivots that deliver real results like 5X revenue growth, $2B in unlocked annual revenue and national awards won for the first time in the organization’s history.
Grounded in systems thinking, decades of martial arts, and a global lens shaped by years working across Asia and Europe, my approach blends technical precision with human insight. I hold degrees in computer science, systems engineering, and organizational design, plus certifications in AI strategy and executive coaching, I have a knack and passion for being able to architect change and drive it.
Whether you're navigating a business transformation or a personal reinvention, I can help you make that change a reality and proceed with courage, clarity, and purpose.
