About Nina Marie
Nina Marie McDonnell built a practice around appellate work. She moved from classroom to courtroom and settled into the particular rhythm of appeals: careful record review, tight brief writing, and precise oral argument.
Early in her career she climbed the learning curve that every appellate lawyer faces. She spent years refining how to frame legal issues so they survive the scrutiny of higher courts. That work required patience and an eye for detail. It also required an ability to distill complex trial records into clear legal narratives.
Her professional path led steadily toward appellate litigation. She has appeared in Missouri courts and holds membership in the bar of the United States Supreme Court. Those admissions allow her to pursue questions at both the state and federal levels. She handles tasks common to appellate practice: drafting briefs, preparing petitions for review, and arguing before panels of judges.
Colleagues and court filings show McDonnell works across a range of cases that reach appellate stages. She takes on criminal and civil appeals, and she has managed cases that involve procedural and substantive law issues. Her approach is methodical. She places emphasis on preserving appellate issues at trial and on presenting them clearly on the record.
McDonnell participates in the professional life of her city and state. She is a current member of The Missouri Bar and of The Lawyers Association of St. Louis. She also holds membership in the Supreme Court of the United States Bar. Those affiliations give her regular contact with the appellate bar and with practitioners who handle intricate post-trial work.
She practices from McDonnell Appeals, LLC, where the firm’s name reflects the narrow practice area she pursues. The office handles the full range of appellate work: briefing, oral argument, petitions for review, and post-disposition filings. Her current practice handles appellate matters in Missouri and federal courts.
