Neyhart, Anderson, Flynn & Grosboll

What Neyhart, Anderson, Flynn & Grosboll does

Neyhart, Anderson, Flynn & Grosboll is a private San Francisco-based law firm founded in 1935 that has practiced exclusively union-side labor law since its inception. The firm represents labor unions, union members, and labor-management trust funds across California and Nevada, with a particular concentration in transit industry unions (Amalgamated Transit Union), construction trades (United Association of Plumbers/Pipefitters, IBEW electrical workers), and Taft-Hartley joint labor-management employee benefit trust funds. The firm claims to represent more ATU Local Unions in California than any other law firm.

The firm's core services include collective bargaining negotiations, labor arbitration, administrative agency proceedings before the NLRB and PERB, ERISA compliance and collections, wage and hour class action litigation, and general preventive law counseling. The trust fund practice covers pension plans, health and welfare plans, and apprenticeship plans across nine IBEW-NECA benefit funds and multiple UA benefit funds. The wage and hour class action practice has secured over $25 million in settlements for transit industry employees regarding unpaid meal and rest periods.

The firm operates as a partner-led boutique with 5-6 active attorneys, including Richard K. Grosboll (employee benefits specialist, 38 years of Taft-Hartley experience, former ABA Welfare Benefits Section Co-Chair), Benjamin K. Lunch (wage and hour class action lead, partner since 2013), Lois H. Chang (ERISA partner), and Manuel Alcantar-Robles. The firm generates revenue through hourly billing, flat fees, and retainer arrangements, with no public pricing disclosure. Client acquisition is driven entirely by professional reputation and decades-long referral networks within the labor movement rather than active marketing. The firm is not branded as technology-forward and uses only standard legal practice management tools. William J. Flynn retired in 2025, and the firm relocated to 369 Pine Street, Suite 400 in San Francisco's financial district as of March 1, 2026.
