L J Soldinger Associates

What L J Soldinger Associates does

L J Soldinger Associates (LJSA) is a privately held, founder-owned certified public accounting firm founded in 1989 by Larry J. Soldinger and headquartered in Deer Park, Illinois (northwest suburb of Chicago). The firm operates as a full-service CPA practice across five interconnected service lines: Accounting & Assurance (audit, review, compilation, IFRS compliance), Tax Planning (preparation, strategic planning, compliance, controversy resolution, international and state tax), Mergers & Acquisitions (business valuations, due diligence, transaction structuring, quality of earnings, financing assistance), Public Company Services (SEC filings, IPO and secondary offering support, SOX 404, reverse mergers), and Business Consulting & Advisory (forensic accounting, fairness opinions, litigation support, bankruptcy and turnaround). The firm is registered with the Public Company Accounting Oversight Board (PCAOB) and inspected triennially, and is a member of the AICPA's Center for Public Company Audit Firms. It has received a 'no comment letter' on all aspects of its practice in every AICPA Quality Review since the program's inception, and the SEC has ranked it among the top worldwide audit engagement leaders in multiple years (4th in Q4 2019, 6th in Q4 2023, 7th in Q4 2025).\n\nLJSA generates revenue entirely through professional service fees across audit, tax, advisory, and consulting engagements. The firm employs 11–50 professionals organized around partner-led service lines and supports clients ranging from large SEC-registered public companies to closely-held family businesses, high net worth individuals, and startups. Client industries include cannabis (a niche the firm has served since 2013), technology and biotech, oil & gas, sports/media/entertainment, food and beverage, apparel/retail, healthcare, and highly regulated multi-state enterprises. Distribution is direct: inbound inquiries via phone, email, and website, supplemented by professional referrals and IR Global's international member network, which gives LJSA effective reach across more than 50 countries. Pricing is engagement-based and not publicly disclosed.\n\nThe firm does not operate proprietary technology platforms or AI/ML systems; its competitive differentiation rests on regulatory credentials, a 35-year operating history, sector expertise (notably cannabis and emerging tech), and demonstrated public-company audit quality. Ownership remains with the founding family (Larry Soldinger and son Benjamin Soldinger, a consulting partner) and firm principals, with no private equity, venture capital, or parent company ownership. There are no subsidiaries, no funding rounds, and no M&A history. Marketing relies on the firm's website, LinkedIn, Facebook, and Twitter presence, earned media coverage in Accounting Today and The Tax Advisor, and IR Global Steering Committee visibility rather than paid advertising.
