Biographical Information

Geoffrey M. Trachtenberg is a partner at the firm who focuses on personal injury, litigation and appeals, particularly related to motorcycle injury and wrongful death cases. He is Board-Certified in Personal Injury and Wrongful Death litigation, a distinction requiring a significant amount of trial experience that is given to less than 1% of attorneys.

Geoff graduated from Boalt Hall School of Law at the University of California, Berkeley. Upon graduation, he served as a law clerk to the Honorable Gary L. Taylor, U.S. District Court for the Central District of California, and then practiced with the law firm of Irell & Manella, LLP in Newport Beach, California.

Geoff is well-known amongst his peers, earning their respect for his honesty and dedication to justice:

“While the rest of us operate on 24 hour days, Geoff must have figured out a way to get at least 30 hours of accomplishment fit into each day. He has earned the respect of top lawyers throughout the legal community. Geoff Trachtenberg has shown the ability to simply achieve more than most others, a result of the combination of his impressive work ethic and legal ability.” — M. Breyer, Esq.

“Geoff and I worked together on a very complex matter and I got to know him well. He has a brilliant grasp of the case law, excellent people skills, extensive trial experience and does not back down from a challenge. He has been a leader among trial lawyers for many years and now serves in a statewide leadership position with the State Bar. I strongly endorse him and would not hesitate to refer family and friends to him.” — L. Entrekin, Esq.

“Geoff has one of the sharpest legal minds I’ve come across in my 37 years as an attorney. His legal analysis is brilliant, and he’s skillful at developing theories that advance the law and the interests of his clients. He’s a dedicated trial attorney, who works hard to obtain justice for his clients.” — H. Snyder, Esq.

Geoff is also a well-recognized expert in the area of medical liens and subrogation rights. He regularly speaks on the topic and is the co-author of the Arizona Personal Injury Lien Law & Practice Guide, a comprehensive publication on state and federal third-party recovery rights.

Geoff is an executive director of the Arizona Association for Justice, which awarded him the Volunteer of the Year award for three consecutive years. He serves as a Judge Pro Tempore with the Maricopa County Superior Court and volunteers his time with a number of organizations, including the Southwest Center for HIV/AIDS, the Arizona Brain Injury Association and assisting poor and indigent families with free legal services.

Recently, he was elected by his colleagues to serve on the Executive Council on the Board of Governors for the State Bar of Arizona. The four-person Executive Council leads the Board of Governors which itself oversees the Bar’s $15 million annual budget and licenses more than 17,000 attorneys throughout the state.
