About Daniel Joseph
Daniel Joseph Koewler studied at the University of Saint Thomas, where he earned a Bachelor of Science in 2001. He went on to law school at the University of Minnesota, graduating with a J.D. in 2007. Those years set the academic foundation for a career centered on criminal law and courtroom practice.
He entered practice in 2008 as a lawyer at Ramsay Law Office. That early work placed him in courtrooms across Minnesota and introduced him to federal practice. He is licensed in Minnesota and is admitted to practice before the U.S. Supreme Court and the U.S. District Court for the District of Minnesota. Over time his caseload has increasingly involved contested matters in state and federal courts.
Koewler's association work runs parallel to his courtroom work. He has been a member of the National College for DUI Defense since 2010. In 2014 he took on leadership roles at two state organizations. He serves as secretary of the Minnesota Society for Criminal Justice and as chairman of the Amicus Curiae Committee for the Minnesota Association of Criminal Defense Lawyers. He joined the Executive Council of a state criminal law section in 2013 and helped found the DUI Defense Lawyers Association in 2015, a group in which he remains active. These roles have put him in the position of shaping amicus activity and professional programming rather than acting as a trial court litigator alone.
Colleagues describe him as a lawyer who spends substantial time on DUI and criminal defense matters. His work spans pretrial motions, plea negotiations and trials when cases proceed. He handles issues that arise in state courts and those that require attention in federal forums, including matters that touch on constitutional claims and procedural questions linked to search, seizure and evidence.
Outside the courtroom, Koewler’s association roles require writing and review of briefs, coordination on amicus projects and participation in continuing legal education. He appears regularly at professional meetings and contributes to discussions about state-level criminal justice policy and practice. That activity complements the litigation work and keeps him engaged with peers who litigate similar issues.
He continues to practice law in Minnesota, maintaining admissions that allow appearances in federal court and before the U.S. Supreme Court, and he concentrates his current practice on criminal defense and DUI-related litigation.
