Insights

Independent Growth Grassi is a large, independent, employee-owned advisory firm with a significant middle-market and public-company client base. This suggests sales opportunities in strategic advisory, tax, and accounting services for growing mid-market firms seeking a stable, owner-driven partner rather than PE-backed firms.

Financial Leadership Recent leadership expansions in tax and forensic practices, plus NY-based growth, indicate opportunities to upsell advanced tax planning, transfer pricing, and litigation support services to high-net-worth individuals, closely held businesses, and expanding nonprofit clients.

High-Net-Worth Focus The integration of Hoffman Mulligan and emphasis on high-net-worth and tax advisory capabilities point to cross-sell prospects for specialized estate, trust planning, and complex tax structuring services to affluent individuals and family offices.

Global and Sector Reach Grassi’s sector diversification (construction, manufacturing, financial services, healthcare, real estate, nonprofit) and global reach through PrimeGlobal create opportunities to target cross-industry advisory packages, scalable from local to multi-national clients seeking integrated solutions.

Digital Transformation Adoption of technologies like SAP, cloud platforms, AI tools (ChatGPT, Copilot), and analytics stack signals readiness for efficiency-driven engagements such as technology-driven outsourcing, data analytics for compliance, and automation-led improvements that can be offered as value-added services to clients.
