About
Abigail Coburn is a partner at Ryan, Miller & Coburn in Missoula, Montana, where Coburn focuses on criminal defense, including DUI, appellate, domestic-violence, and white-collar matters. The practice includes serious criminal cases in Montana state and federal courts. Coburn works on matters that require careful review of the facts, governing law, and the client’s practical objectives. The work stays closely connected to the decisions, risks, transactions, or disputes that brought the client to counsel.
Coburn earned a J.D. from the University of Montana School of Law in 2017 and completed undergraduate study at Carroll College. During law school, she was selected for the trial team and competed in advocacy events. This academic background supports legal analysis, research, writing, and problem solving. The training also supports careful review of rules, records, documents, and options within the lawyer’s current practice.
Coburn has experience with working for a local criminal-defense firm before opening her own boutique practice in 2019 and later partnering with Ryan and Miller. Her practice includes trial and appellate work and representation in Montana state court, federal court, and the Ninth Circuit Court of Appeals. This experience supports organized matter development and preparation for negotiation, transactions, administrative proceedings, trial, or appeal when required.
Abigail Coburn was recognized as Rookie of the Year by the Montana Association of Criminal Defense Lawyers early in her career. Coburn maintains active memberships in organizations focused on criminal defense and DUI representation. The combination of education, prior roles, and current practice supports careful legal judgment and disciplined client service.
