Katten Muchin Rosenman expanded its Corporate and Litigation practices with the arrival of five new attorneys in its Dallas office.

Greg Hidalgo joined as a partner in the Corporate practice. Barrett R. Howell and Brandon N. McCarthy became partners in the Litigation practice, while former federal Judge Jorge A. Solis joined as special counsel. Aaron P. Pinegar joined as special counsel in the firm’s Transactional Tax Planning practice.

“Continuing to grow our Dallas office underscores our ongoing commitment to better serve our clients and meet their business needs in the North Texas region, an economic frontrunner,” said Katten Chairman Roger P. Furey. “This new team brings a wealth of knowledge and deep ties to the Dallas business community that will help us continue to boost our profile in Texas and bolster our capabilities in handling a wide range of client matters.”

Hidalgo is recognized for his experience in mergers and acquisitions, joint ventures and other corporate matters spanning multiple industries, from private equity and real estate to health care and energy. He uses his prior public financial experience with a Big Four accounting firm when working with clients to achieve their business and financial objectives.

Howell focuses his practice on white-collar criminal defense, specializing in investigating and litigating complex civil and criminal cases. He has experience conducting internal investigations and defending companies and executives before federal and state agencies, including the Department of Justice, FBI and the SEC. He has advised clients in whistleblower lawsuits, government investigations and enforcement actions involving allegations of securities and health care fraud, bribery and corruption.

McCarthy concentrates his practice on fraud and white collar crime, with capabilities and experience handling and defending allegations of health care and securities fraud, conspiracy, embezzlement, financial crimes and public corruption.

Judge Solis was nominated by President George H.W. Bush in 1991 and served as a U.S. District Judge for the Northern District of Texas for 25 years before retiring from the bench in 2016 as the district’s chief judge.

Pinegar has counseled clients with respect to federal income taxes on a wide variety of transactional and planning matters, including mergers and acquisitions, private equity transactions, spin-offs, debt and equity offerings, joint ventures and bankruptcies.
