Milligan & Company, LLC

What Milligan & Company, LLC does

Milligan & Company, LLC is a Philadelphia-headquartered certified public accounting and consulting firm founded in 1985 by John Milligan, a former PricewaterhouseCoopers manager. The firm operates as one of the largest minority-owned CPA firms in the United States, with offices in Philadelphia, Cherry Hill, and Washington DC, and a workforce of 11-50 employees. Over four decades, Milligan has overseen more than $30 billion in public funds through its government consulting engagements, conducted over 500 FTA Triennial Reviews nationwide, and completed six consecutive AICPA Peer Reviews without any Letter of Comments.

The firm's service portfolio spans four core practice areas: Audit & Assurance (government audits, single audits under OMB Circular A-133, ERISA audits, internal controls); Tax & Accounting (tax preparation, planning, IRS representation, business consulting); Transportation & Capital Project Consulting (FTA Triennial Reviews, Financial Management Oversight Reviews, DBE program development, Title VI compliance); and Diversity & Civil Rights (workforce diversity assessments, DBE program implementation, cultural competency training). In early 2020, the firm created Milligan Consulting, LLC as a distinct entity to provide dedicated consulting services in transportation, diversity, and economic development.

Milligan's business model is relationship-based professional services delivery, with revenue generated through custom engagement-based pricing determined by scope, complexity, and client type. The firm serves federal agencies (FTA, FAA, DOT, Commerce), state transportation departments, municipal governments, transit authorities (SEPTA, NJ Transit), non-profit organizations, and small-to-medium businesses. Distribution is exclusively direct sales through RFP responses, relationship-based engagement, and referrals. The firm is founder-owned with no external institutional investment, private equity backing, or public listing.
