Nathan J. Kunz is a highly experienced commercial litigator with a career spanning more than 17 years. He is a trusted legal professional in Arizona with a proven record that shows his exceptional skills and expertise in handling a wide range of complex legal matters. He has extensive experience representing clients in nearly every issue in contract enforcement and interpretation and on related equitable and tortious claims (such as unjust enrichment, equitable estoppel, fraudulent misrepresentation, and tortious interference). He has also successfully represented clients on appeal and in actions arising from noncompetition agreements, business divorce, and defamation—and in defending franchisors against claims of consumer fraud brought by a putative class.
Prior to joining Coppersmith Brockelman, Nathan honed his litigation skills at a National Am Law 100 firm where he became a partner as well as at a boutique firm, where he focused on commercial litigation, class action defense, and state and federal appeals.
