Tronconi Segarra & Associates LLP

What Tronconi Segarra & Associates LLP does

Tronconi Segarra & Associates LLP is a privately held, licensed New York State CPA firm founded in 1985 and headquartered in Williamsville, with a second office in Lockport. The firm operates under an alternative practice structure: Tronconi Segarra & Associates LLP delivers auditing and attestation services, while a related advisory entity, TSA Advisors LLC, provides tax, accounting, and non-attest advisory services in compliance with the AICPA Code of Professional Conduct.

Its core services are organized into three primary lines — auditing and attestation (financial statement audits, reviews, compilations, employee benefit plan audits, internal audit and controls), tax/accounting/advisory (corporate and personal tax planning and compliance, cross-border services, SALT, entity selection, M&A advisory), and small business services (bookkeeping, financial statement preparation, advisory). The firm also provides transaction and M&A advisory, estate and succession planning, executive compensation, and fractional/virtual CFO services. No proprietary technology platform is disclosed; service delivery is partner-led and engagement-based.

The firm generates revenue through professional services fees on recurring (attestation, compliance) and project-based (advisory, M&A, fractional CFO) engagements. Clients span manufacturing, education, hospitality, distribution, and supply chain — including Delaware North Companies, University at Buffalo Foundation, Bryant & Stratton College, American Changer Corporation, Seal & Design, and Hanes Supply — with publicly cited tenures exceeding 20 years. Go-to-market is sales-led and relationship-driven, supported by a website, blog/newsletter publishing, social channels, and a formal RFP intake process.
