What Lopata, Flegel & Company does

Lopata, Flegel & Company LLP is a privately held, full-service accounting and management consulting firm organized as a Missouri Limited Liability Partnership. The firm traces its origins to 1933 as the St. Louis office of a national accounting firm and became an independent entity in 1990; it operates today from a single headquarters at 600 Mason Ridge Center Drive, Suite 100, in St. Louis, Missouri. Patricia Myers has served as Managing Partner since 2024, succeeding Allan Epstein who continues in an Audit Principal capacity.

The firm delivers services across four interconnected lines: Assurance (audits, reviews, compilations, agreed-upon procedures), Tax Services (compliance, multi-state planning, audit representation, estate/gift/trust planning), Business Solutions (transactional accounting, outsourced controllership/CFO, business planning), and Consulting (M&A advisory, due diligence, purchase price allocations, litigation support, forensic accounting). These services are deployed against six industry verticals — manufacturing, construction and real estate, wholesale and distribution, retail and restaurant, service industry, and private equity and emerging business — plus high-net-worth individuals, trusts, estates, and not-for-profit organizations.

The business model is engagement-based professional services pricing (fixed fee or hourly), delivered directly by partners and managers with the firm publicly committing to transparent client billing. Go-to-market relies on content marketing (educational articles), community involvement (Midwest Manufacturing Leaders First Fridays Forum, Sharp & On Point Speaker Series, Lopata Cares), social media presence, and referral-driven relationships, supported by a 99%+ client retention rate. The firm has 11-50 employees, partners averaging 20+ years of public accounting experience, and relies on third-party platforms (QuickBooks, Sage 50, Xero, NetLink client portal, LeapFile, CPACharge) rather than proprietary technology for both internal and client-facing operations.
