• Federal Criminal Defense Attorney Sean Buckley recently won big in a massive $100 million federal criminal trial where his client was accused of defrauding the TRICARE federal healthcare program. His client, along with 12 other defendants, were accused of conspiring to bill the government for expensive compounded pharmaceuticals like pain and scar creams that were allegedly not needed.  His client was found NOT GUILTY. It’s one of Texas’ biggest federal criminal cases brought in connection with the government’s nationwide criminal investigation into compounding pharmacies and their marketing operations that have received federal money., 2019
• Notable wins include: an unprecedented “Not Guilty” verdict in a $120 million Federal Health Care Fraud Conspiracy and Money Laundering trial where his client was accused of defrauding the TRICARE Federal Healthcare Program. His client was found NOT GUILTY.

• Case Dismissed: Sean Buckley recently defended me against serious and false criminal allegations made by my ex-husband during our divorce. I stood to lose everything including my freedom. Mr. Buckley handled my case with the utmost professionalism, judgment, and skill. His efforts led prosecutors to dismiss all charges before trial. Thank you for giving me my life back!     , 2017
• Mr. Buckley served as trial co-counsel and diplomatic liaison for U.S. businessman Larry Davis, who was charged in the Dominican Republic in 2016 with trafficking 980 kilograms of cocaine and heroin. Following months of coordinated diplomatic efforts through the U.S. Department of State and a highly publicized two-month trial in Santo Domingo, a Dominican federal court found Larry Davis “Not Guilty” of all charges. The takeaway from this case is that a massive volume of drugs does not – in itself – mean that a case cannot be successfully defended. Each case is unique, and previous successful results do not predict successful outcomes for future cases.    , 2016
