About Tom Callahan

I’m a Manager in accounting advisory with a focus on controllership operations, finance transformation, and project leadership. I partner with Controllers and senior finance leaders to help organizations scale their accounting functions, improve close and reporting processes, and execute complex initiatives with clarity and discipline.Over the past several years, I’ve led end‑to‑end delivery of accounting and operational projects for PE‑backed and public companies, often in fast‑growth or highly complex environments. My work has included close acceleration, accounting process centralization, system implementations, IPO readiness, and cross‑functional finance initiatives.I’m most effective in roles that require:• Owning projects from planning through execution• Leading and developing teams• Translating accounting requirements into practical, scalable processes• Communicating clearly with senior stakeholdersRecent experience includes reducing month‑end close timelines from 20+ days to under 10 days, centralizing multi‑brand accounting teams into a shared services model, and leading Workday and Salesforce implementations supporting finance operations.I enjoy roles that sit at the intersection of accounting, operations, and project management, and I’m particularly interested in opportunities where I can help build or modernize controllership functions rather than operate solely in technical accounting silos.Core areas of focus:Controllership Operations | Close Optimization | Finance Transformation | Project / Program Management | Team Leadership | System Implementations | Carve‑Out & Spin Readiness
