About Andrew I.
Andrew I. Martinez began his legal path after studying philosophy at Northern Arizona University, where he earned a Bachelor of Arts in 2004. He continued his education at the University of Wisconsin–Madison and received his J.D. in 2007. Those academic years shaped his interest in argument, ethics and the practicalities of courtroom work.
He entered practice in Wisconsin soon after law school and joined Martinez & Ruby, LLP. He became a partner in 2008. That early elevation defined the next phase of his career: handling trial work, supervising client files and taking on firm responsibilities alongside casework.
Martinez works in Wisconsin courts. He has been a member of the Wisconsin Association of Criminal Defense Lawyers since 2010 and participates in that professional community. His membership indicates a sustained engagement with criminal defense practice and with colleagues who handle contested matters in state court.
At Martinez & Ruby, LLP he handles a range of criminal matters and related proceedings. He represents clients in hearings and trials, prepares pleadings and manages investigatory work. His daily work is a mix of courtroom appearances, client consultations and legal drafting.
Colleagues describe his approach as methodical. He emphasizes preparation for hearings and clarity when explaining options to clients. He balances litigation work with the administrative duties that come from serving as a partner at a small firm. That balance includes case strategy, client relations and oversight of file management.
Outside of casework he stays connected to the defense bar through local professional activities and continuing legal education. Those connections help him keep up with procedural changes and evolving case law that affect criminal practice in Wisconsin.
Martinez’s career arc—from undergraduate study in philosophy to a law degree and partnership at a Wisconsin firm—reflects steady progression within a single state’s legal system. He continues to practice at Martinez & Ruby, LLP in Wisconsin, where his work focuses on criminal defense and related state-court matters.
