“Jimmy Cool successfully defended me and my company in a multi-million-dollar commercial arbitration. His attention to detail, dedication, patience, and analytical and strategic thinking, combined with his hard work led us to victory against a leading national law firm. He is an excellent trial attorney, and his command of countless complicated and technical issues spanning more than eight years of corporate business operations and history allowed us to focus on the right points at the right time and to successfully defend against our opponent’s claims.”

Shyam Byra, CEO, SQA Labs, Inc.

“James is a consummate strategist, with a firm grasp of the technical and medical details of cases. In our experience of working with attorneys on a national level, James is part of a distinguished echelon, capable of keen analyses and detailed focus on pertinent aspects, regardless of case type. Skills like his will always ensure that his clients’ concerns are optimally represented, regardless of their matter.”

Dr. Michael Valdisseri, Chairman and CEO of Bio-Sim Corporation


Jimmy Cool is a litigator and trial attorney whose practice emphasizes serious or catastrophic personal injuries, commercial disputes between closely held companies, professional administrative or regulatory action, and a variety of matters involving the rights of public employees.

Jimmy's practice is not defined by a particular area of law or subject matter; instead, he focuses on representing good people – ranging from families and individuals to closely held companies and professional organizations such as the Arizona Court Reporters Association – who need responsive legal guidance. His mission is to counsel his clients about their options and to work together to achieve the outcome or resolution that best meets their goals. Jimmy seeks to help his clients find cost-effective and practical solutions to serious problems.

Personal Injury

In the personal injury arena, Jimmy represents victims of negligence, medical or professional malpractice, and nursing home elder abuse. He has significant experience representing the victims of traumatic brain injuries and in dealing with the related medical and legal issues. His notable recent cases include the following:

  • Successfully litigated to a confidential six-figure settlement for the victim of an industrial accident that required three weeks of hospitalization.

  • Recovered $600,000 for a student who suffered a serious spinal injury in a rear-end collision.

  • In a negligent security claim, achieved a confidential settlement against multiple defendants on behalf of a financial industry executive who was assaulted by a fellow patron outside an upscale nightclub.

  • Achieved a six-figure settlement on behalf of an elderly, wheelchair-bound woman who was seriously injured following cataracts surgery due to the failure of the surgical center staff to escort her to her vehicle, as required by the center's policies.

  • Reached a confidential six-figure settlement on behalf of retirees whose retirement property was severely damaged in the midst of construction by a carelessly ignited fire on a neighboring property.

Business Law

In addition, he represents closely held businesses and the individuals who own them in commercial disputes regarding corporate governance and commercial transactions and in defense of governmental regulatory and administrative actions. Recent cases:

  • Vindicated a wrongfully sued local internet technology company and won the complete dismissal of a mid-six-figure claim.

  • Actively represents two northern Arizona medical marijuana dispensaries in business and regulatory compliance matters.

  • Successfully defended a physician in a breach of contract, fraud and racketeering claim in which the plaintiffs claimed more than $500,000 in alleged damages. After an eight-day trial, the 10-member jury returned a unanimous defense verdict, and our client was awarded $120,000 in legal fees and costs.

  • In an eight-day commercial arbitration, co-counseled with Shawn Aiken in successfully defending the owners of a tech-industry staffing company against claims for damages totaling more than $4 million for alleged self-dealing, oppression, and mismanagement.

  • Actively represents Arizona's largest association of court reporters in business and professional regulatory matters.

Public Labor Law

Jimmy also has broad experience in the field of public labor law and has represented or counseled dozens of public employees facing administrative discipline.

  • Successfully advised and led the team that negotiated the first collective bargaining agreement between an Arizona county Sheriff’s Department (Pinal County) and its deputies.

  • Formerly represented dozens of Arizona law enforcement officers in matters involving employee rights, due process, merit system appeals, public agency labor relations, tribal sovereign immunity, civil rights and discrimination.

  • Prevailed in an administrative trial before a three-person county merit board and overturned the 30+ hour suspension of a sheriff's deputy for allegedly damaging a county vehicle due to negligence.

Civil Litigation

Finally, Jimmy's general civil litigation practice has included a broad variety of contested matters in superior court and in administrative proceedings:

  • In a civil rights claim of unconstitutional imprisonment, represents a young mother imprisoned for 92 days, just six weeks after giving birth to her first child, for a crime she did not commit.

  • Played a major role on the team of Aiken Schenk lawyers in the only successful legal challenge to the Arizona Department of Health Services' regulations for dispensing medical marijuana.

  • Represented an Arizona political candidate under federal investigation for alleged abuses of power intended to advance the client's candidacy.

Professional Activities

While attending law school at Arizona State University, James earned distinction as one of the most highly decorated oral advocates in school history by winning virtually every oral advocacy competition he entered. He was named the Outstanding Oral Advocate, Class of 2010, and received national recognition for his excellence in oral advocacy. At ASU, he won the 2009 Jenckes Closing Argument Competition and the 2008 Oplinger Closing Argument Competition and was the recipient of the AAJ’s National Trial Advocacy Scholarship in 2011.
