WASHINGTON DC – Mayer Brown announced today that Albert “BJ” Stieglitz has joined the firm as a partner in its Global Investigations & White Collar Defense practice in Washington DC. He joins Mayer Brown from Alston & Bird.

“BJ is one of the premier investigations and enforcement defense lawyers in the market, bringing an exceptional combination of senior government leadership, domestic and international enforcement experience, and practical business judgment," said Ken Wainstein, leader of Mayer Brown's Global Investigations & White Collar Defense practice. "His experience handling significant fraud and corruption matters on the prosecution and the defense side, coupled with his global perspective from his time inside and outside of government and his strong client relationships, makes him an outstanding addition to our team and further strengthens our ability to advise clients facing their most complex challenges in the US and overseas."

BJ advises companies and individuals on internal investigations, government enforcement actions, litigation, and compliance matters involving securities fraud, the Foreign Corrupt Practices Act, and other complex and often cross-border issues. He has advised clients across a broad range of industries, including healthcare, life sciences, energy, retail, financial services, manufacturing, private equity, technology, and transportation.  

Before entering private practice, BJ spent nearly 13 years with the US Department of Justice, including in senior leadership roles in the Criminal Division's Fraud Section, where he led and oversaw significant fraud and FCPA investigations, tried multiple federal criminal cases to verdict, and was twice awarded the Attorney General’s Award for Distinguished Service. He also was selected as the DOJ’s first-ever dual secondee to the UK’s Serious Fraud Office and Financial Conduct Authority, a role in which he led investigations of a variety of UK offenses, negotiated two UK deferred prosecution agreements, and advised on transatlantic enforcement issues and interagency relationships. 

“Mayer Brown has built an industry-leading investigations and white collar defense practice, and the opportunity to join it is tremendously exciting" said BJ. "The firm's truly global platform and the outstanding multidisciplinary expertise of its lawyers position it to help clients facing increasingly complex enforcement and compliance challenges in ways that very few firms can. I am excited to join such an exceptional team at this time of strategic growth, and I look forward to contributing to the firm’s continued success."

"BJ's arrival reflects our continued investment in strategic areas that are increasingly important to our clients," said Andrew Olmem, managing partner of Mayer Brown's Washington DC office. "His distinguished public service background, international experience, and reputation as a trusted advisor make him a tremendous addition to our office and our firm. We are delighted to welcome him to Mayer Brown.”
