What McCorriston Miller Mukai MacKinnon does

McCorriston Miller Mukai MacKinnon LLP ("M4 Law") is a Honolulu-headquartered full-service law firm founded on May 1, 1989, by William C. McCorriston and Clifford J. Miller, with a second office on Kauai. The firm operates as a limited liability partnership with 30+ attorneys supported by paralegals, legal assistants, and administrative, IT, finance, and office-services staff (overall headcount band 51-100). It is co-led by Co-Managing Partners Joel D. Kam and Laurel K.S. Loo, with no parent company, no outside investment, and no disclosed M&A history.

The firm delivers legal counsel across 16 practice areas, including Litigation & ADR, Real Estate & Development, Corporate & Business Law, Trusts & Estates, Public Finance, Construction, Health Care, Immigration, Administrative Law & Government Affairs, Native Hawaiian Rights, Constitutional Law & Civil Rights, Creditors' Rights & Restructuring, Energy & Public Utilities, Intellectual Property, Nonprofit Organizations, and Timeshares & Vacation Ownership. Notable specializations include Hawaii-specific expertise in Native Hawaiian land and water rights, the State's distinctive land tenure system, land court titles, and resort/timeshare law, supported by attorneys with prior government service (e.g., former Kauai County Attorney, State Land Use Commission Chair, special counsel to City & County of Honolulu). The firm is independently recognized by Best Lawyers (Tier 1 in 16 areas, 2026), Chambers USA, Super Lawyers, Benchmark Litigation, and Martindale Hubbell AV Preeminent.

M4 operates on a traditional professional services model: legal services are billed to clients (individuals, businesses, government agencies, and enterprises across hospitality, healthcare, real estate, energy, financial services, and nonprofit sectors) under quote-based / negotiated fee arrangements, with rates not publicly disclosed. Go-to-market relies on peer recognition, legal directory rankings, attorney credentials, community involvement, and long-tenured client relationships rather than active marketing campaigns. The firm runs no proprietary technology platform, app, or API, and there is no disclosed revenue, funding, or external ownership.
