The full scope—from the books to the boardroom

Audit-grade bookkeeping & financial reporting

Institutional-quality records, reconciliations, and reporting that stand up to scrutiny. We’ve prepared and defended books through audits, due diligence, and regulatory review for over three decades.

Tax strategy, preparation & controversy

Sophisticated tax planning and compliance for individuals and entities at every scale. We minimize liability, manage estimated payments and extensions, and represent clients when it goes to the next level.

Payroll & employment compliance

Full payroll processing, multi-state and local tax filings, and compliance with labor and benefits regulations. No learning curve—we’ve handled complex structures and audits for decades.

Strategic advisory & leadership counsel

Cash flow, budgeting, M&A support, and the kind of strategic advice that comes from having seen every market and every mistake. We’re in the room when the big decisions get made.

Decades in the room when it matters

We don’t learn on your dime. Our senior team brings the judgment, precision, and institutional memory that only comes from thirty-five-plus years of seeing every cycle, every audit, and every curveball. When the stakes are real, serious clients turn to us.
