About David G.
David G. Casey completed his legal studies at Thomas M. Cooley Law School, beginning in 2005 and earning his J.D. in 2009. He arrived in the profession at a time when courts and clients were navigating both traditional courtroom practices and evolving procedural rules. His education set the stage for a steady practice in the Midwest.
Soon after law school, Casey established himself in Wisconsin. He is authorized to practice in Wisconsin and before the Federal Circuit, allowing him to handle matters at both the state and certain federal appellate levels. That combination has shaped the contours of his work, moving between trial strategy and appellate writing depending on the case.
Casey has been active in professional circles that support criminal defense work. He holds membership in the Wisconsin Association of Criminal Defense Lawyers and has a long association with the Marathon County Association of Criminal Defense Lawyers, where he served as president. Those roles put him in regular contact with other defense attorneys and with local issues affecting practice and procedure.
His day-to-day practice centers on criminal defense. He prepares cases for trial and represents clients in hearings and jury trials. When cases proceed beyond trial, he prepares appellate briefs and argues appeals. He handles a mix of state court matters and federal filings, drawing on courtroom experience to inform appellate strategy and vice versa.
Colleagues describe him as precise in preparation and practical in court. He tends to favor clear, direct arguments and thorough record development. That approach often means spending significant time on discovery, witness preparation, and crafting post-trial motions when needed. He balances trial readiness with attention to the preservation of issues for appeal.
Beyond the courtroom, Casey participates in the professional community through seminars and association activities. His past leadership in Marathon County reflects a willingness to take on organizational responsibilities that affect local practitioners. He also maintains membership in statewide groups that offer training and networking for criminal defense lawyers.
Now practicing in Wisconsin, Casey continues to handle criminal matters at both trial and appellate levels. He manages a caseload that includes state prosecutions and federally related issues, and he maintains active participation in bar and defense organizations as part of his ongoing practice focus.
