Donahue & Horrow LLP

What Donahue & Horrow LLP does

Donahue & Horrow LLP is a California-based plaintiff-side law firm founded in 2006 and headquartered in El Segundo, with co-founders Thomas E. Donahue and Michael B. Horrow serving as founding partners. The firm operates two practice verticals: (1) Insurance Denial Litigation, covering long-term disability, ERISA denials, long-term care, life insurance, AD&D, health insurance, and property insurance claim disputes; and (2) Medical Malpractice Litigation, with a particular specialization in birth injury cases (cerebral palsy, shoulder dystocia, HIE, brachial plexus injuries, wrongful birth) plus broader brain injury and wrongful death matters. The combined legal team comprises four named attorneys with over 80 years of cumulative experience, supported by approximately five additional staff for a 9-person total.

The firm serves individual policyholders and families across California and Washington, with physical office coverage in roughly 16 California cities plus a Spokane, Washington regional office, and remote intake via toll-free phone and web forms. Cases are evaluated through free initial consultations, and the firm operates exclusively on a contingency fee basis, meaning clients pay no attorneys' fees or costs unless recovery is obtained. The firm's value proposition is anchored in the partners' prior insurance defense experience, which provides insight into insurer denial rationales, and is evidenced by over $300 million in cumulative client recoveries including Ninth Circuit appellate victories against major insurers such as Unum and Sun Life, and individual settlements ranging from $30K to $8M+. The go-to-market mix combines inbound content marketing (blog, essential guides, social presence on Facebook and LinkedIn), referral partnerships with workers' compensation attorneys, community sponsorship (Tour de Pier), and direct-to-consumer intake. Revenue model is professional services on contingency, with operating geographies limited to California and Washington; the firm has no disclosed funding, M&A, or institutional investor participation and is structured as a Limited Liability Partnership.
