Fractional COO leadership for growing nonprofits.
Operational systems and management for nonprofits experiencing growth or transitions. Accounting infrastructure, internal controls, federal and state grant portfolios, HR / IT / admin modernization, and board reporting partnership.

The operational counterpart to the CFO seat.
Where the CFO owns the numbers, the COO owns the machinery that produces them. We stand up the internal controls, audit-ready workflows, grant-compliance calendars, and HR / IT / admin systems that a growing nonprofit needs before its next major expansion. Board reporting is a partnership: the CFO delivers the finance narrative, the COO delivers the operations story underneath.
