FGMK, LLC

What FGMK, LLC does

FGMK, LLC is a privately held professional services firm headquartered in Bannockburn, Illinois, with additional offices in Chicago and Oakbrook Terrace serving the greater Chicagoland market. Founded in 1969 and operating for nearly 60 years, the firm delivers accounting, tax, advisory, governance/risk, and financial leadership services to mid-market and closely-held businesses, high-net-worth individuals, and not-for-profit organizations across more than 27 industry verticals, including asset management, private equity, real estate, healthcare, manufacturing, broker-dealers, cannabis, gaming, and technology. FGMK is consistently recognized among the Top 100 accounting and advisory firms in the United States by Accounting Today, ranked #66 nationally in 2024.

The firm operates across five core service lines: Financial Reporting (audit, assurance, fund administration, statutory audits, employee benefit plan audits, and surprise examinations), Tax Services (federal, state, local, international, R&D credits, cost segregation, estate and succession planning), Advisory Services (M&A, management consulting, performance improvement, turnaround/restructuring, forensic and valuation, compensation consulting, and employee benefits consulting), Governance, Risk and Controls (cybersecurity, internal audit, SOC reporting), and Financial Leadership Solutions (interim and outsourced finance and accounting staffing). Service delivery is partner-led and supported by a Client Portal (ClientAxcess) for secure document exchange and ConvergePay for billing; the firm does not develop proprietary technology products.

FGMK generates revenue exclusively through professional services fees across the five service lines, with no public pricing disclosures. Client acquisition is driven by partner relationships, industry reputation, thought leadership content, webinars, and consistent recognition by industry publications. The firm extends its service surface through wholly owned and affiliated entities including Centric Wealth Management, FGMK Payroll, FGMK Insurance, and FGMK Financial Services, and accesses international markets through the TAG Alliances network. Clients are served nationwide and internationally, though the physical footprint remains concentrated in the Chicago metro.
