Sheehan, Phinney, Bass & Green

What Sheehan, Phinney, Bass & Green does

Sheehan, Phinney, Bass & Green is a New England-based business law firm founded in 1937, headquartered in New Hampshire with five offices spanning New Hampshire, Massachusetts, and Vermont. The firm operates with 75+ attorneys organized across 15 practice areas, providing services to mid-market businesses, entrepreneurs, financial institutions, healthcare organizations, and high-net-worth individuals. Core practice coverage spans corporate, litigation, real estate, intellectual property, tax, and estate planning, enabling the firm to serve as a general outside counsel for clients requiring cross-disciplinary advice in the regional market.

The firm's business model is the traditional law firm partnership/professional association model: billable-hour and engagement-based fee arrangements with clients, supplemented by retainer relationships for ongoing corporate and estate planning work. Revenue is generated through attorney services across multiple offices, with no disclosed alternative-fee or technology-enabled product lines. The firm does not appear to operate a technology platform, managed service, or alternative legal services entity; its offering is fundamentally human-judgment-based legal advice delivered through partner-led teams. No AI, automation, or proprietary technology assets are referenced in the available data.

Commercially, the firm is differentiated by its exclusive New Hampshire membership in Lex Mundi (a global network of independent law firms), granting it cross-border referral capabilities that local competitors cannot replicate. Third-party validation includes sustained inclusion in Chambers USA rankings across multiple practice categories in both 2025 and 2026. Recent strategic activity—Portsmouth office expansion and a senior Co-Chair appointment in Estate Planning—indicates targeted reinvestment in growth markets within the existing footprint rather than transformative geographic or vertical expansion.

Emerging players

They represent a structural threat to mid-size firms' commoditized practice areas.
