What Nigro Karlin Segal Feldstein & Bolno does

Nigro Karlin Segal Feldstein & Bolno (NKSFB) is a Los Angeles-based professional services firm founded in 1981 that provides business management, tax, audit, royalty, touring, athlete, and forensic accounting services to high-net-worth individuals in the entertainment, sports, and business sectors. The firm operates seven offices across the United States and the United Kingdom with 650+ employees and 53 Partners, and serves clients that include 12 of the last 15 Super Bowl Halftime Show performing artists, top recording artists, film and television professionals, and professional athletes. Its core service lines—Business Management, Tax, Audit, Recording Artist Services, Touring Services, Athlete Services, and Forensic Accounting—are delivered through a direct sales model built on partner-led engagement, referrals from entertainment attorneys and managers, and relationships with industry guilds and unions.

NKSFB has grown both organically and through a sustained program of practice mergers, with eight acquired practices integrated between 2007 and 2022, including David Bolno (2014), Press Schonig Rosenthal (2014), Gudvi Oppenheim (2018), David Weise & Associates (2019), Neuman + Associates (2019), CRM Management (2020), Howard Capital Management (2020), Avery & Greig (2022), and Ross Bennet Smith (2022). In 2018, NKSFB was acquired by Focus Financial Partners (NASDAQ: FOCS), becoming a subsidiary within the publicly traded wealth management platform while retaining its brand and operating model. The firm operates through two primary legal entities—NKSFB, LLC for non-accounting services and Nigro Karlin Segal & Feldstein, LLP for accounting and audit work—using a partnership governance structure with 53 Partners.

The firm generates revenue through recurring professional service fees on customized engagements, billed monthly with quote-based pricing tailored to client scope and complexity. Underlying technology consists of proprietary internal software for bookkeeping, accounts payable, cash receipts, bank reconciliation, payroll booking, and general ledger review, used by account executives to serve clients. Marketing and client acquisition rely on word-of-mouth referrals, industry reputation, university campus recruiting (USC, CSUN, Loyola Marymount, Cal State LA, Cal Poly Pomona, UCLA), editorial coverage in industry publications (LA Business Journal, Hollywood Reporter, LA Times Studios), and social channels (LinkedIn, YouTube). Pricing and revenue figures are not publicly disclosed.
