Perry Hamilton Consulting is a Chicago-based advisory firm providing fractional CFO and COO services to nonprofit organizations locally and remotely. Founded by Karen Hamilton, a nonprofit finance and operations executive with more than 20 years of experience, the firm offers senior-level leadership to organizations that need stronger financial oversight, more effective operations, or both—without the cost of a full-time executive.

CFO services include budget development and monitoring, financial consulting, payroll, and audit preparation and support. COO services focus on administrative systems, workflow design, compliance and document management, governance support, and standard operating procedures. The aim is to help nonprofits improve accountability, build reliable back-office systems, and scale with greater confidence.

Perry Hamilton Consulting emphasizes practical, collaborative support grounded in hands-on nonprofit experience. Rather than providing recommendations and stepping away, the firm works alongside client teams to address challenges and strengthen day-to-day operations. Karen’s background includes managing multimillion-dollar budgets, leading audits, implementing financial systems, and supporting boards and leadership teams.
