About

I lead strategic finance and long-range planning for a multi-billion dollar institution, partnering with C-suite executives on capital allocation, forecasting, fee revenue analysis, and enterprise-level financial decision-making. My work spans bespoke financial modeling, multi-year scenario planning, and executive reporting that translates complex analysis into clear decisions. Previously, I advised Fortune 50 companies at EY-Parthenon and Deloitte on M&A, growth strategy, and operating model transformation, delivering diligence, valuation, and integration analyses supporting multi-billion-dollar transactions. I hold a CMA and a BBA from the University of Notre Dame (Mendoza College of Business).
