What Robbins, Tunkey, Ross, Amsel, Raben, & Waxman, P.A. does

Ross Amsel Raben Nascimento, PLLC (successor to Robbins, Tunkey, Ross, Amsel, Raben & Waxman, P.A.) is a boutique criminal defense law firm headquartered in Miami, Florida, with a lineage dating to 1977. The firm provides exclusively federal and state criminal defense representation, with no other practice areas, and is staffed by three partners holding over 105 years of combined experience: Robert G. Amsel (since 1982), David Raben (39 years), and Managing Partner Joseph E. Nascimento (15+ years). Service lines include federal criminal defense, state criminal defense, white collar defense, healthcare fraud defense, complex government investigations, IRS whistleblower representation, appellate practice, drug crimes, violent crimes, sex crimes, and forfeiture cases. The firm operates in Florida state and federal courts and extends nationwide through pro hac vice admissions.

The firm serves individuals facing criminal investigation or prosecution, medical practitioners facing healthcare fraud allegations, executives and business owners facing criminal exposure, and IRS whistleblowers. Client acquisition is driven by direct phone contact (24/7 line) and professional referrals rather than marketing. Pricing is quote-based per engagement and not publicly disclosed; no SaaS, subscription, or productized revenue model exists. The business is a partner-owned limited liability company with no external investment, parent company, or public listing.

The firm holds AV ratings from Martindale-Hubbell, Best Lawyers recognition for White Collar Defense in Miami, Florida Super Lawyers listings, and NACDL President's Award recognition. The underlying technology is minimal: a marketing website (crimlawfirm.com) on Squarespace, standard phone and email communications, and no proprietary platforms, APIs, or technology products. The firm's competitive advantage derives entirely from partner expertise, courtroom results, and accumulated reputational capital over 45+ years.

Broad incumbents

• Bilzin Sumberg Baena Price & Axelrod: Miami-based full-service commercial law firm with a Litigation group handling white-collar and government investigation matters. Competes for the same South Florida client base but offers broad corporate, real estate, and tax services alongside criminal defense.
• Holland & Knight: Large national law firm with significant Miami presence and a Litigation section that includes white-collar criminal defense. Competes for similar matters in South Florida but operates as a full-service firm with significantly broader practice offerings.
• Ropes & Gray: Major global law firm with a leading government enforcement and white-collar defense practice. Competes with the subject firm on complex federal investigations and healthcare fraud matters, but operates at significantly greater scale and geographic reach.
• Akerman LLP: Major Florida-based full-service law firm with a white-collar and government investigations practice group. Comparable as a Miami-headquartered competitor offering criminal defense among many other practice areas, but with broader corporate, real estate, and litigation services.
