Chief People Officer | Organizational Transformation | Leadership & Talent Strategy | AI Enablement | Business Performance
Santa Monica, California, United States
I help organizations evolve from the company they are today into the company they need to become tomorrow.
Over the past two decades, I have partnered with founders, CEOs, boards, and executive teams to lead organizational transformation during periods of rapid growth, strategic reinvention, leadership transition, cost pressure, global expansion, and business model change.
My work sits at the intersection of business transformation and human transformation. I help organizations strengthen leadership capability, redesign structures, improve talent density, modernize People systems, and build the operating discipline required to execute strategy effectively.
Increasingly, I am focused on how AI is reshaping work, leadership, organizational design, and workforce capability. I believe People leaders have a unique opportunity to help organizations rethink not only who does the work, but how work gets done.
Throughout my career I have built and led People organizations across technology, consumer, fintech, consulting, and venture-backed businesses ranging from hypergrowth startups to global matrixed enterprises. I am known for combining business acumen, analytical rigor, and organizational insight with a leadership style grounded in empathy, candor, and accountability.
My toolbox includes:
People Operations
• People and HR Strategy • Culture & Values Design
• Talent Acquisition • L&D • Performance Management
• Workplace Solutions • HRIS Implementation
• Total Rewards • DEI Programs • M&A Integration
