What Maher Duessel does

Maher Duessel is a privately held certified public accounting firm founded in 1989 and headquartered in Pittsburgh, Pennsylvania, with five additional offices across the state (Butler, Harrisburg, State College, Erie, Lancaster). The firm provides audit, tax, and advisory services exclusively to government and non-profit organizations, including counties, municipalities, state agencies, school districts, colleges and universities, foundations, religious institutions, professional associations, housing authorities, transportation agencies, and for-profit businesses receiving federal funds. Core service lines include Financial Statement Audits, Single Audits (approximately 185 engagements annually), Employee Benefit Plan Audits, Non-Profit Tax Services, Client Accounting and Advisory Services (CAAS), and a Government Specialty Services practice covering ACFR/AFR assistance, bond and debt services, DCED audits, HUD REAC filings, and GASB implementation.

The firm operates on a relationship-driven, sales-led B2B professional services model, delivering services directly through its six Pennsylvania offices to clients both in-state and nationally. Pricing is project- and engagement-specific with no public rates disclosed. Technical differentiation rests on deep specialization in federal compliance regimes (Uniform Guidance, Title IV, Yellow Book) and governmental accounting standards (GASB 84, 87, 88, 89, 104), supported by a multi-tiered team of partners, principals, and senior managers each focused on distinct sub-domains.

Maher Duessel generates revenue through four primary streams: Audit Services (financial statement audits, Single Audits, employee benefit plan audits, Yellow Book audits), Tax Services (IRS Form 990/990-T for non-profits), Client Accounting and Advisory Services (CAAS), and Government Specialty Services (ACFR/AFR, bond/debt, DCED). Marketing channels include an industry insights blog, email newsletter, LinkedIn/Twitter presence, CPE seminars, and participation in professional associations such as PASBO and PICPA. The firm maintains AICPA peer review compliance as a quality control standard, and its ownership structure is consistent with a partner-led CPA firm with no identified parent company or institutional investor.
