Thomas V. Sjoblom



Prior to entering private practice, Thomas spent nearly 20 years at the SEC in Washington, D.C. For the first five years, he served as special counsel in the SEC's Division of Market Regulation (now Division of Trading and Markets), where he advised the SEC on fraudulent broker-dealer and trading market practices, and became the in-house expert on market manipulation. For the next fifteen years, he litigated those issues on behalf of the SEC as assistant chief litigation counsel in the SEC's Division of Enforcement. He primarily focused on market manipulation but also litigated and tried cases involving fraudulent securities offerings, false periodic reports, insider trading, financial fraud, balance sheet enhancements, FCPA, and violations of the Investment Advisers Act of 1940. While at the SEC, Thomas also served as a special assistant U.S. attorney for the Central District of California, the Western District of New York, and the Eastern District of Pennsylvania. In that capacity, in conjunction with the U.S. attorney's office for each district, he investigated broker-dealers for over-subscribed IPO (pump and dump) fraudulent offerings, and co-prosecuted several individuals indicted for market manipulation, bank fraud, and tax fraud.

Additionally, Thomas has deep international experience. He appeared on behalf of the U.S. government in several court enforcement proceedings in Europe and the Netherlands Antilles. Thomas has also been called upon by several European and Asian governments and securities exchanges to advise them on investigating and prosecuting market manipulation and market abuse schemes, as well as on drafting statutes, regulations, and codes of conduct outlawing market abuse and insider dealing, including England's HM Treasury, the Market Directorate of the European Union, the Finansinspektionen in Sweden, and the securities regulator in the Philippines.

Thomas also represents clients in the sports and entertainment industry, including professional golfers, golf management companies and facilities, and event sponsors.

In addition, Thomas is the co-chair of the firm’s Global Anti-Corruption practice, which provides comprehensive global guidance to companies and individuals involved in international business transactions or subject to governmental investigations.
