What Thompson Accounting does
Thompson Accounting is a privately held CPA firm headquartered in San Jose, California, specializing in forensic accounting and expert witness testimony. The firm was founded by Michael S. Thompson, CPA, who brings 40+ years as a CPA and 30 years as a consulting and expert witness, and is now led by his daughter Megan Thompson as Managing Partner. The firm holds itself out as qualified to act as an expert witness in twelve counties throughout California, and combines 60+ years of team experience in family law forensics. The practice operates from a single San Jose office with an estimated 10-15 team members including staff accountants, project management, and operations leadership. There are no patents, technology platforms, or AI/ML capabilities disclosed; the product is human expert analysis supported by standard professional services tooling (ShareFile for document exchange, third-party payment processors for billing).
The firm's core offering is forensic financial analysis and expert witness testimony for family law matters, with a suite of report sub-products: business valuations, marital standard of living reports, reimbursements and post-separation accounting, asset and property claims, stock option/RSU and retirement plan allocation reports, income available for spousal and child support calculations, civil litigation support (partnership disputes), and probate estates and trusts accounting. Service delivery begins with a consultation and conflict check, followed by a retainer-based engagement with hourly billing; supplemental retainers may be requested if scope expands, and unused balances are refunded.
Thompson Accounting serves individuals and families involved in divorce proceedings and civil litigation, plus family law attorneys who refer clients and require expert witness support. Revenue is generated through professional services billing on a retainer-based, hourly engagement model with multi-year engagements possible. Client acquisition is driven by attorney referrals, court appointments, direct client inquiries through the firm website, and professional community involvement — Megan Thompson is a former CalCPA chapter President, current Education Foundation trustee, and active conference speaker. The firm has no disclosed funding rounds, operates from one location, and has no M&A, partnership, or acquisition activity in evidence.
