Launching Lavely & Singer in 1980 with Jay Lavely, Singer cultivated a litigation powerhouse that rebranded to Singer Weinsten Wolf & Jonelis LLP in March 2026, honoring partners Michael Weinsten, Brian Wolf, and David Jonelis while forming a new Executive Committee. His aggressive tactics have shielded A-list stars in landmark defamation suits, privacy invasions, and employment disputes, earning the firm Daily Journal's nod as a leading California boutique. Though entrenched in Los Angeles entertainment circles, Singer's practice extends to business, political, and sports sectors without direct Miami ties, commanding influence across major U.S. markets.
