Ashcroft Law Firm

Mr. Sullivan is a Boston-based partner of the Ashcroft Law Firm, and has extensive experience in whistleblower law and criminal conduct spanning virtually every substantive area of fraud — including securities, healthcare, bankruptcy construction, tax, bank, insurance, identity, investment schemes, mortgage assistance and appraisal, and false claims. Mr. Sullivan has served in government for half his career, first as a state district attorney and then as a federal prosecutor. In 2001, shortly after 9/11, the President of the United States nominated him and the United States Senate confirmed his appointment to serve as United States Attorney for the District of Massachusetts.

During his tenure as federal prosecutor (U.S. Attorney), the Office was the national leader in combating fraud in the health care industry, recovering more than $4 billion for the United States, and settling the largest health care fraud in the history of the Justice Department at the time, which resulted in a payment of $2.3 billion. Sullivan’s Office also was responsible in investigating hundreds of fraud-related matters extending to virtually every substantive area of fraud, including securities, healthcare, bankruptcy construction, tax, bank, insurance, identity, investment scheme, mortgage assistance and appraisal, and false claims.

Currently, Mr. Sullivan’s work focuses primarily on the areas of health care and government program fraud, corporate compliance and ethics, and corporate corruption. He routinely advises and represents individuals and companies in both civil and criminal matters, such as investigations, enforcement actions, regulatory compliance, and litigation.

Mr. Sullivan has represented victims of various types of fraud, including individuals who have been harmed by illegal payments to government officials by competitors (under the Foreign Corrupt Practices Act), and those who have been fraudulently induced to donate funds to a sham charity (implicating state and federal fraud laws). He has worked on behalf of an organization that had funds embezzled by its own attorney, and advised client companies on strengthening internal compliance and ethical programs in the wake of improper conduct.
