About Joshua B.
Joshua B. Mayes is an Arizona-educated lawyer who moved quickly from student to courtroom. He read history and law in two state institutions and followed that training into appellate and trial work.
He completed his undergraduate studies at Arizona State University and earned his Juris Doctor from the University of Arizona. While at law school he served on the Arizona Law Review as an editor. Those years sharpened his legal research and writing and introduced him to complex briefing and editorial oversight.
After law school he served as a clerk to The Honorable Earl Carroll of the U.S. District Court for the District of Arizona. The clerkship gave him a front-row view of federal procedure, evidentiary rulings and the day-to-day mechanics of a busy trial court. It also offered the kind of practical courtroom exposure that many attorneys later draw on in litigation settings.
Mayes is admitted across a broad swath of Arizona and federal courts. He is authorized to practice in all Arizona state courts, the Arizona Court of Appeals, the Ninth Circuit Court of Appeals and the U.S. District Court for the District of Arizona. His admissions also include Superior Courts in Maricopa, Pima, Coconino and Yavapai counties, as well as various justice and municipal courts. That range reflects frequent appearances at different judicial levels rather than a single appellate or trial niche.
He is a member of MayesTelles PLLC, where he works alongside other attorneys in a firm setting. Colleagues describe him as methodical in his preparation and steady during hearings. He has handled tasks typical of trial practice: drafting pleadings, arguing motions, preparing witnesses and participating in oral argument. His background on law review and at the federal clerkship informs the way he shapes legal memos and briefs.
Mayes’s work is grounded in courtroom practice and procedural familiarity. He draws on experience in both state and federal dockets when advising clients on case strategy and litigation posture. He currently practices at MayesTelles PLLC, concentrating on litigation matters in Arizona’s state and federal courts.
