Justin J. Janzen

Justin Janzen obtained a Bachelor of Philosophy degree with Honors from Trinity Western University in 2002. He went on to complete his Juris Doctorate, magna cum laude, at the University of La Verne in 2005. Upon graduation, he worked at a civil defense firm in San Bernardino that focused on medical malpractice defense and insurance defense of healthcare providers. He had a particular interest in the intentional torts that increasingly accompany medical malpractice claims. He has dispensed with many such claims, including battery, fraud, willful misconduct, and elder abuse, at the initial stages of litigation, often eliminating punitive damages claims in the process. Since joining Thompson & Colegate in 2018, his practice has expanded to include more general litigation claims and public entity law. While in practice, Justin completed a Master’s in Bioethics and Public Health Policy and teaches law courses for the communications department at the University of La Verne.
