William D. Nelson, Firm Founder

Personal injury attorney William D. Nelson has practiced law in Tucson, Arizona for more than 30 years, always representing victims of others' wrongdoings. His clients include people who have been injured in automobile accidents, injured by defective products, traumatized by sexual assault or who have suffered serious injury due to dangerous premises conditions. He has significant experience representing the elderly, disabled and other vulnerable persons.

Originally from the Midwest, Mr. Nelson graduated from Miami University in Oxford, Ohio with a bachelor's degree in Psychology in 1973. He went on to earn his law degree from University of Kentucky Law School in 1979. In the same year, he was admitted to the Arizona State Bar and the United States District Court for the District of Arizona. In 1984, he was admitted to the State of Washington Supreme Court, and in 1997, to the United States Court of Appeals for the Ninth Circuit.

Mr. Nelson began his legal career as a prosecuting attorney at the Pima County Attorney's Office in Tucson, Arizona. Assigned to the felony crimes unit as a trial attorney, he handled a wide variety of criminal cases, including murder, armed robbery, kidnapping, sexual assault, fraud and embezzlement, trying in excess of 50 cases to a jury. The experience proved invaluable in honing his litigation and advocacy skills.

In 1986, Mr. Nelson joined a personal injury law firm in Tucson, representing victims in cases involving motor vehicle collisions, medical malpractice, premises liability and products liability. He established his own personal injury practice eight years later to focus on helping honest people with serious injury claims. By maintaining a small caseload, he is able to provide personalized, individual attention to each of his clients throughout the legal process.

Lawyers and judges in the Tucson legal community have distinguished Mr. Nelson with an AV® Preeminent™ rating by Martindale-Hubbell®, the definitive guide to law firms and attorneys in America. Based entirely on peer review, the AV rating is the highest attainable level for professional skill and ethics for any attorney or law firm.

Mr. Nelson is Board Certified in Wrongful Death and Personal Injury Litigation by the State Bar of Arizona Board of Legal Specialization, a distinction among Tucson personal injury attorneys. To be board certified, an attorney must be engaged in wrongful death and personal injury litigation as a substantial focus of the lawyer's practice, and must possess a high degree of skill, thoroughness, procedure, evidence and ethics in the field. Competency and integrity are verified through a rigorous written examination and peer review process. Once board certified, an attorney must attend yearly continuing legal education in the area of specialization.
