Over the course of more than 35 years of practicing law, Cam has represented clients in civil and criminal litigation, conducted internal investigations for public companies, and defended against government investigations. His practice has involved forums and proceedings throughout the state of Texas, as well as in Arkansas, California, Colorado, Florida, Iowa, Kansas, Kentucky, Louisiana, Mississippi, Montana, Pennsylvania and Wisconsin. Ranging across the panoply of legal issues and discrete topics, Cam’s cases relate to a broad spectrum of federal statutes enforced by a number of federal agencies, including the IRS, SEC, HHS, FDA, ICE, and FDIC.

Representative categories illustrating Cam’s diverse experience and more than 35 years developing his expertise and reputation in these areas of his practice include:

Cam’s clients have included executives, professionals, corporations, and other business entities. He has represented them in administrative proceedings, investigations, court actions, and appeals.. Such matters occasion negotiations with representatives of the Department of Justice, including those from United States Attorney’s offices in various districts, as well federal law enforcement agents representing the FBI, IRS, HHS-OIG and ICE. Although he always strives to find ways to resolve matters short of indictment and trial, Cam has tried cases in federal district courts in Texas, Iowa, Montana, and Colorado.
Cam has represented clients in civil tax proceedings at all levels of the IRS administrative process, including Appeals and Post Appeals mediation. He has litigated matters pending before the Tax Court, in federal district courts, and the United States Court of Federal Claims. His criminal tax experience includes all stages of pre-indictment administrative enforcement actions and grand jury investigations. He has successfully defended clients at trial against charges of conspiracy, tax fraud, and making false statements to IRS agents.
Cam has conducted numerous internal investigations on behalf of publicly held companies’ audit committees, general counsel, and boards of directors. He has investigated allegations of embezzlement, bribery, and kickbacks, as well as violations of federal statutes related to health care, money laundering, and financial institutions. Following the conclusion of many of those investigations, clients have requested Cam to refer his findings to the appropriate law enforcement agencies, and to work with them as needed over the course of their investigations. His efforts in such referrals have resulted in convictions for theft, wire fraud, and conspiracy to commit bank fraud.
Cam has represented clients in numerous SEC investigations and enforcement actions. The investigations have related to a wide variety of alleged violations of federal securities laws, including those governing insider trading, false statements and other types of securities fraud.
Cam has defended clients in civil suits brought under the False Claims Act, the federal RICO statute, as well as in litigation between individuals and business entities. His representations have included mediations, trials, and appeals.
Cam is committed to providing legal services to those who cannot afford to retain counsel. He has devoted hundreds of hours to representing such individuals through his more than 20 years of service on the Northern District of Texas’ Criminal Justice Act panel. For each of the past 5 years he received recognition by Hunton & Williams for providing 100 hours or more in the service of pro bono clients. During that time he worked with other Dallas attorneys and representatives of the Human Rights Initiative of North Dallas to try two asylum cases in the Dallas Immigration Court. He intends to provide pro bono representation to deserving individuals through the office of Zachry Law PLLC.
