Legal Team Brings Extensive Civil and Criminal Defense Experience, Including SEC and DOJ Background

Carlton Fields is pleased to announce the expansion of its securities litigation and SEC enforcement defense practice with the addition of the legal team of Thomas V. Sjoblom and Austin L. Jackson. Sjoblom joined the firm as a shareholder in Washington, D.C., and Jackson joined as an associate in Los Angeles, both from the Law Offices of Thomas V. Sjoblom PLLC.

Sjoblom and Jackson are trial lawyers who handle sophisticated and complex securities matters, including government investigations, shareholder lawsuits, white collar criminal matters, and parallel regulatory and criminal proceedings. They represent board chairs, CEOs, and officers and directors of publicly traded and privately held companies; financial institutions, including banks, brokers, investment advisers, investment companies, and hedge funds; lawyers, both in-house and outside counsel; and accountants.

In addition to 20 years in private practice, Sjoblom brings decades of experience as a former Securities and Exchange Commission litigator and a special assistant U.S. attorney. He expands Carlton Fields’ deep bench of former SEC attorneys and federal prosecutors across the country.

“Carlton Fields is known for its excellence in securities litigation and white collar criminal defense, and I am excited to bring my niche practice to a national platform with a number of complementary services,” Sjoblom said.

Added John E. Clabby, chair of Carlton Fields’ Securities and Derivative Litigation Practice: “Tom and Austin bring a wealth of experience that enhances our existing services in high-stakes securities fraud litigation and SEC investigations. We are thrilled to welcome them to the firm.”

Sjoblom has defended clients in matters involving financial fraud, including SEC periodic reports, financial statement presentation, options backdating, and intercompany transfers within hedge fund complexes. His cases have also included Sarbanes-Oxley certifications and compliance; insider trading; market manipulation; best execution practices of mutual funds, investment advisers, and brokers; and the defense of hedge funds. He has also defended clients accused of international securities fraud and violations of the Foreign Corrupt Practices Act. Further Sjoblom has represented the U.S. government in international court proceedings and advised foreign governments on investigating and prosecuting market manipulation.

Jackson’s practice focuses on complex securities litigation, white collar criminal defense, and enforcement actions prompted by federal and state regulators. He has represented domestic and foreign companies, executive officers, and directors in connection with alleged violations of the securities laws, Foreign Corrupt Practices Act, anti-money laundering, and antitrust laws.

Both have handled matters involving the SEC, the Commodities Futures Trading Commission (CFTC), the U.S. Department of Justice (DOJ), and various state attorneys general offices.

Sjoblom earned his LL.M. from Georgetown University, his J.D. from William Mitchell College of Law, and his B.A., phi beta kappa, summa cum laude, from the University of Minnesota.

Jackson, one of five attorneys to join Carlton Fields’ Los Angeles office in the past month, earned his J.D. from California Western School of Law and his B.S. from North Carolina State University.
