Tessa K. Muir brings a decade of experience as a former federal prosecutor and Army JAG officer to provide outstanding legal advice and representation to her clients as a defense attorney. Ms. Muir is an aggressive litigator who will effectively challenge the government in tough cases by knocking out evidence, avoiding and reducing charges, and winning cases. As a prosecutor, she oversaw approximately 100 federal grand jury investigations and successfully served as lead attorney in numerous federal and military trials. She has specialized expertise in violent crime, drug trafficking, complex computer crimes, sex crimes, child pornography, misdemeanors, juvenile offenses, white collar crime, and corporate investigations.


Ms. Muir knows how the system works from the inside out. As a federal prosecutor at the U.S. Attorney’s Office for the Western District of Michigan, Ms. Muir worked closely with the FBI, Homeland Security Investigations (HSI), the Drug Enforcement Administration (DEA), and other federal, state, and local agencies. She understands the challenges of collecting and using evidence in a criminal case, and she uses that to her clients’ advantage to fight for the best results.

  • Drug cases (possession, distribution, manufacturing, importing, trafficking)
  • White collar investigations (internal corporate investigations, tax fraud, wire fraud, embezzlement)

  • Appeals (challenging convictions and sentences with the higher-level court)


Ms. Muir also helps people who are being investigated, accused, or called as a witness in criminal cases. If you think you might be suspected of a crime, don’t wait to get expert advice. Ms. Muir will advocate for your rights and help protect you from criminal charges during any level or type of criminal investigation. 

If you are being called as a witness at a grand jury, prelim, hearing, or trial, you can rely on Ms. Muir’s expert guidance to get you through while protecting your rights and privacy.


Ms. Muir also has previous experience as an in-house corporate attorney for a large international tech company. As in-house counsel, she oversaw internal fraud investigations and defended the company against lawsuits worldwide. 

If your company is experiencing internal fraud or is under investigation, you need someone who understands confidentiality, risk management, and mitigating public fallout. Ms. Muir is a trusted corporate advisor, especially when confidentiality and privacy are of the utmost concern.
