Tessa K. Muir
SBBL Law, PLLC
Tessa K. Muir is an accomplished trial attorney as a former federal prosecutor and former Army JAG officer. As an Assistant US Attorney in the Western District of Michigan, Tessa served as the lead prosecutor in hundreds of federal criminal cases and Sixth Circuit appeals. 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 sheriffs’ offices throughout Michigan. Now, she uses that knowledge to understand weaknesses in an investigation and areas where law enforcement and investigators made critical errors.
She has earned commendations for her work as a federal trial attorney from the FBI, Homeland Security, and the State Bar of Michigan. Since 2015, she has been selected by fellow attorneys and federal judges in the Western District of Michigan as a Steering Committee member and instructor for the Hillman Trial Advocacy Program —the district’s premier federal trial practice program.
Tessa founded and leads SBBL Law’s Title IX practice group and has become a national leader in the field. She represents students, staff, and faculty members who are either the victim (complainant) or the accused person (respondent) in Title IX sexual harassment and sexual assault cases at schools and colleges nationwide. She puts her background as a federal prosecutor and defense attorney to work to ensure the Title IX investigation process is as fair and thorough as possible for her clients. Her expertise and track record in this field are unrivaled, and she brings a deep understanding of Title IX laws and policies to fight for a fair and just outcome in every case. As a Title IX attorney, she has successfully advocated for clients from five years old through college grad students and professors.
