Haynes and Boone Welcomes Assistant U.S. Attorney Sean McKenna


DALLAS – Sean McKenna, a veteran lawyer with almost 15 years of health care experience, has joined Haynes and Boone, LLP as a partner in the firm’s White Collar Defense Practice Group, where his practice will focus on defense of health care fraud and abuse, white collar, and health care regulatory matters.

For the last 10 years, McKenna served as Assistant U.S. Attorney for the U.S. Attorney’s Office of the Northern District of Texas, where he was responsible for investigating, prosecuting, and resolving hundreds of civil, criminal and administrative investigations, matters and cases during his 14 years as a Government attorney. He also served as chair of the North Texas Procurement Fraud Working Group, a member of the Texas Medi-Medi Steering Committee, and as point of contact for HIPAA privacy-related issues.

“Sean’s strong background in white collar and healthcare matters will be an asset for our clients in this complex regulatory environment,” said Bill Morrison, partner in the firm’s Healthcare and White Collar Defense Practice Groups. “He offers a wealth of knowledge and experience to the firm as we continue to grow.”

McKenna’s previous government experience includes serving as an Associate Counsel for the Office of Counsel to the Inspector General in Washington, DC and Assistant Regional Counsel for the Dallas Region, Office of the General Counsel, within the U.S. Department of Health and Human Services. During that time he negotiated and resolved integrity agreements and False Claims Acts cases against health care providers, providing guidance and interpretation on statutory and regulatory issues, and advising Medicare, Medicaid and other federal agencies on billing and reimbursement issues. McKenna also has appeared before administrative and bankruptcy proceedings on behalf of federal programs, including Medicare and Medicaid.

Haynes and Boone’s White Collar Criminal Defense practice group defends companies and executives against charges of criminal misconduct and related civil claims. The group’s matters span varied industries and involve concerns of criminal misconduct under antitrust, banking, environmental, false claims, healthcare, and securities laws. With the support of the firm’s more than 500 attorneys in 13 offices, the group can defend clients nationally and internationally.
