Welcome to Byrne & Nixon - Providing Legal Defense Since 2003

Experience · Reliability · Ethics

At Byrne & Nixon LLP, we provide exceptional legal advice, representation, and results to corporations, other business organizations, executives, and other individuals involved with “white collar” issues in criminal cases, grand jury proceedings, government investigations, and criminal cases and trials. In addition, based upon our extensive experience in handling criminal matters in state and federal courts, we have the ability to provide first-rate legal representation to those charged with, or under investigation for a vast array of crimes in state and federal court. Moreover, our vast trial experience – more than 100 federal and state jury trials to verdict – enables us to effectively represent a wide range of clients involved in civil litigation matters. Dedicated to recognizing and meeting client needs, we offer practical solutions to complicated legal problems affecting individuals and businesses throughout California and the United States.

Areas of Practice


Our practice is nationwide, and focuses on areas of law in which our lawyers have significant experience. Mark and Dan were federal prosecutors in the white collar section of the United States Attorneys’ Office – and gained substantial experience using grand juries and investigating and prosecuting white collar crimes – so now we focus on defending those matters. Prior to Dan’s tenure at the U.S. attorney’s office, he worked as a state prosecutor in the white collar section of the Los Angeles district attorneys’ office, so he is uniquely qualified to represent individuals and companies being investigated or charged with state crimes. It is common for criminal matters, especially white collar matters, also to involve parallel proceedings – i.e., regulatory investigations related to the alleged criminal conduct – so our Firm routinely represents clients facing investigations or inquiries involving various state and federal regulatory agencies, including the SEC, FDIC, FINRA, IRS, FDIC, FTC, and California DMV.
