Relentless Post-Conviction Relief
Unwavering Advocacy.
Meticulous Defense.
Adam has achieved a series of overturned convictions on behalf of clients seeking post-conviction relief, including multiple life sentences. Through meticulous investigation and unwavering attention to detail, he has uncovered exculpatory evidence suppressed by the State—evidence that ultimately proved his clients’ innocence.
He has tried multiple cases before juries in both State and Federal courts, with every jury trial in which he served as lead counsel resulting in not guilty verdicts. Adam has also successfully argued cases before the Louisiana Supreme Court, helping to expand precedent law and solidifying his reputation as a formidable advocate.
After clerking for the Honorable Judge Robert Wyatt and the Honorable Judge Ronald Ware, he joined his father, Terry, and brother, Jonathan, at The Johnson Firm in 2009, where he continues to focus exclusively on high-stakes criminal defense litigation.
Generations of Experience Meet a New Era of Defense
The Johnson Firm has been a trusted part of Lake Charles since 1980. Founded by Terry Johnson and now led by the next generation, the firm reflects decades of earned respect in Southwest Louisiana courtrooms. Adam Johnson and his brother Jonathan grew up immersed in the legal community, learning firsthand the value of preparation, credibility, and understanding how local judges and courts operate. That foundation continues to shape the firm’s approach today.
