Mary Schaub is a senior executive advisor and transformation operator who partners with C-suite leaders to drive enterprise execution through periods of complexity, growth, and structural change. She works as an embedded Chief of Staff–style partner to align strategy, operations, governance, and leadership behavior, ensuring critical initiatives deliver measurable results.

With more than 20 years of experience across Fortune 500 financial services, consulting, and high-growth organizations, Mary has held COO-adjacent, Chief of Staff, and enterprise transformation leadership roles inside global, highly regulated environments. She has led large-scale operating model redesigns, enterprise change portfolios, and workforce transformations impacting 50,000+ employees, with accountability for governance, execution cadence, and outcomes.

Mary brings a rare combination of operational rigor and behavioral insight. She designs execution systems that clarify decision rights, prioritize what matters, and create sustained momentum across complex organizations while addressing the human dynamics that often derail transformation. Her work includes building enterprise PMOs and change offices, redesigning operating and talent models, embedding executive governance, and stabilizing organizations during moments of transition.
