What Nielsen Merksamer does

Nielsen Merksamer is a California-based political law, government law, and lobbying firm organized as the limited liability partnership Nielsen Merksamer Parrinello Gross & Leoni LLP, with offices in San Rafael (San Francisco Bay Area) and Sacramento. The firm serves a national clientele that includes many of Fortune's Top 25 Largest U.S. Companies, plus nonprofits, trade associations, labor unions, public agencies, and high-net-worth individuals. Its core offering is highly specialized legal advice in political and regulatory law — campaign finance compliance, lobbying disclosure, government ethics, ballot measures and initiatives, redistricting and voting rights, election litigation, legislative advocacy, administrative law, and high-stakes constitutional litigation at federal and state court levels.

The firm's practice architecture rests on two pillars: California ballot-measure expertise (where it has served as counsel on most major statewide initiatives and referenda over the past 40 years, including the landmark Proposition 22 defense before the California Supreme Court) and a 50-state national political law compliance practice pioneered by Jason D. Kaune and Steven S. Lucas. Its only "technology" surface is the Essential Ethics bi-weekly newsletter and a client portal that delivers jurisdiction-specific compliance materials and client workshops — the firm explicitly does not develop software products.

Revenue mechanics follow a traditional professional services model: hourly and engagement-based fees for legal counsel, with pricing not publicly disclosed. Go-to-market is enterprise field sales driven by partner-led relationships and reinforced by sustained thought leadership (Essential Ethics newsletter, Super Lawyers, Best Lawyers in America, Chambers USA, and Capitol Weekly recognition). The firm employs 33 professionals across partners, of counsel, and staff, with leadership concentrated among a management committee that includes Kurt Oneto (head of government law), Jason D. Kaune (head of political law), Chris Skinnell (General Counsel), Steven S. Lucas, John J. Moffatt, and Sean Welch.
