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!

have seen Mr. Buckley at work when he won in a massive $100 million federal criminal trial where his client was accused of defrauding the TRICARE healthcare program. His “Not Guilty” verdict shows that he is a consummate professional and one of the best criminal defense trial lawyers in the country. If you are in serious criminal trouble, it would be a mistake not to have him on your legal team.
