About Arianne
Arianne Kerr began her legal career in the Pima County Superior Court, serving as a law clerk in 2014. The year on the bench gave her a close view of courtroom procedures, evidence practice, and the rhythms of trial dockets. It was an early professional chapter that shaped how she approaches case development and written work.
Kerr moved into private practice the following year. In 2015 she joined the Law Office of Keith Singer as an associate. There she handled case files, prepared pleadings, conducted legal research, and worked directly with clients. The role expanded her practical skills and exposed her to the full lifecycle of litigation from intake to pretrial stages.
In 2018 she became a partner at Kerr Bowron, PLLC. That promotion marked a transition from supporting roles to firm leadership. As partner she is charged with supervising staff, guiding strategy in active matters, and maintaining client relationships. Colleagues describe her as steady in court and thorough in preparation. She brings the procedural knowledge from the clerkship and the hands-on experience from earlier firm work to each file.
Her courtroom background informs much of her practice. Years of drafting motions, responding to discovery, and arguing in hearings have made courtroom procedure and case management central to how she approaches disputes. She spends considerable time on legal writing and on-the-record advocacy. Outside the courtroom she focuses on client counseling and case evaluation, aiming to provide clear options and realistic assessments of risk.
Kerr's day-to-day mixes litigation tasks and firm responsibilities. On some days she is in court or in deposition; on others she is mentoring junior lawyers, reviewing briefs, or meeting with clients about case strategy. The arc of her career — clerkship to associate to partner — shows a steady accumulation of courtroom experience and firm-side responsibilities. She now practices at Kerr Bowron, PLLC, representing clients and managing casework.
