I help founders, private equity–backed teams, and CFOs bring structure, speed, and clarity to complex financial environments.

🔷 Business Financial Consulting

From GAAP compliance and audit readiness to financial system optimization and multi-entity reporting, I step into challenging situations and deliver clear, trusted results.

I partner with growing companies, startups, and business owners who are navigating rapid growth, recovering from disorganized systems, or preparing for regulatory events.

Whether you need to clean up your books, implement a new ERP, or prepare for your first audit, I provide hands-on support tailored to your goals—so you can move from chaos to control with confidence.

  • Thorough review and reconstruction of historical records using tech-enabled tools to restore accuracy and compliance.

  • Streamlining close processes for timeliness, consistency, and real-time insights.

  • Preparation and documentation support to ensure you're ready for internal, external, or investor audits—GAAP-compliant, transparent, and defensible.

  • Partnering with your CFO and accounting team to guide organizations through financial change—from new system rollouts and process redesign to restructuring and rapid growth. I ensure smooth transitions by aligning stakeholders, training teams, and embedding best practices that drive adoption, accountability, and long-term operational success.

  • Leading and overseeing accounting systems integration projects from planning to execution. I work closely with your IT team, external consultants, and internal accounting staff to ensure seamless implementation of platforms like NetSuite, QuickBooks, and Sage Intacct—enhancing accuracy, automating workflows, and delivering real-time financial visibility.
