" Tessa K. Muir earned a Juris Doctor (JD), graduating cum laude, from Georgetown University Law Center. She is an accomplished trial attorney and a former federal prosecutor and former Army JAG officer. She served as the lead prosecutor in hundreds of federal criminal cases and Sixth Circuit appeals as an Assistant S Attorney in the Western District of Michigan. She worked closely with and trained federal, state, and local law enforcement agencies on search warrants, computer investigations, and human trafficking, including the Michigan State Police, FBI, DEA, ATF, Homeland Security, police departments, and sheriff’s offices throughout Michigan. SBBL Law is led by former federal prosecutors, government attorneys, and seasoned trial attorneys. In past positions, their partners spent years building cases for the federal government and, as a result, understand how to take them apart to defend their clients effectively. Having worked on the other side and knowing the system from the inside out allows them to walk beside their clients at every step of the process with empathy and a dynamic approach to obtaining the best possible outcome in every case. They pride themselves on strategizing each case’s swift and successful resolution by uncovering every possible defense, whether by dissuading the prosecution from charging in the first place, winning motions to suppress evidence, negotiating a favorable plea agreement, challenging illegal searches and seizures, taking the case to trial, or navigating a complex appeal.
