Maria E O.

CPA with 15+ years of experience across Big 4 audit, institutional fund finance, and hands-on Controller work at high-growth companies. I work with founders, investment managers, and owner-operated businesses that need senior-level finance expertise without a full-time hire. My background spans Ernst & Young (financial services audit), Grosvenor Capital Management ($50B+ AUM fund of funds, NAV validation, investor reporting, SEC filings), and River Financial, a VC-backed Bitcoin brokerage where I was the first accounting hire and built the entire accounting infrastructure from scratch through the company's first external audit and multiple VC fundraises. I take on fractional Controller, fund accounting, and CFO advisory engagements across a range of industries and fund structures. I'm comfortable owning the full accounting function independently and working directly with founders, boards, and external auditors.
