Hayleigh’s practice focuses on appeals and complex civil litigation. Her experience includes state and federal litigation, internal investigations, and government and regulatory matters. Southwest Super Lawyers recognized her as a “Rising Star” in civil litigation. Outside of the office, she serves on the Executive Council for the State Bar’s Appellate Practice Section, on the Board of the Florence Immigrant & Refugee Rights Project, and sits on the Camelback East Village Planning Committee.
Hayleigh also contributes to the Arizona Appeals content for Practical Law (with Eric M. Fraser) and writes for the AZAPP blog. Her article, Going for Broke: Arizona’s Legal Protection of Public Pension Benefits, was cited in a dissenting opinion of the Arizona Supreme Court.
Before joining Osborn Maledon, Hayleigh clerked for the Honorable Mary M. Schroeder of the Ninth Circuit Court of Appeals and spent several years training horses. While in law school, she served as the Editor-in-Chief of the Arizona State Law Journal and was active in the Women Law Students’ Association. Hayleigh also previously served as Senior Vice President of Operations for Fundamental Income Properties, a real estate investment firm backed by Brookfield Asset Management.
