What Roberts Nathan does

Roberts Nathan is an Irish accounting and business advisory firm founded in 1997 and headquartered in Dublin, with a secondary office in Cork. Effective 1 July 2024, Roberts Nathan merged with MHA and rebranded as Baker Tilly Ireland, becoming the Irish member firm of Baker Tilly International, a global advisory network spanning 147 territories, 754 offices, and 50,400 professionals with combined worldwide revenue of $6.8 billion. Vivian E. Nathan is identified as managing partner.

The firm delivers a full-service professional offering across four core lines: Audit and Assurance (external audit and regulatory compliance verification); Advisory (business advisory, corporate finance, insolvency and debt advisory, international business services, global mobility and expatriate services, and sustainability and ESG consulting); Tax (corporate, international, and private client tax); and Financial Outsourcing (payroll, digital accounting services, and bookkeeping). The firm organizes its go-to-market around five industry verticals: Financial Services (including asset management, banking and capital markets, insurance, and FinTech/crypto), Technology, Construction/Infrastructure/Real Estate, Retail/Consumer/Hospitality, and Pharmaceutical and Life Sciences.

Revenue is generated through professional services fees structured as project-based engagements or recurring advisory retainers, with no proprietary technology platform underlying the service delivery. The go-to-market is sales-led, relying on direct enterprise relationships and business referrals, with cross-border referrals sourced through the Baker Tilly International network. Post-merger, the firm has announced plans to create 100 new jobs across audit, advisory, and tax services in Dublin and Cork, with stated intent to double in size in the Irish market.
