Sean’s path to law was non-traditional, and his diverse professional background gives him a distinct perspective on client problem-solving. Before entering the legal field, he worked in horticulture, landscaping, information technology, and non-profit data analysis. These experiences shaped his ability to collaborate across disciplines and inspired his lasting commitment to sustainable development and resource management.

Sean earned his J.D. from Arizona State University’s Sandra Day O’Connor College of Law, where he completed a concentration in Law and Sustainability. While in law school, he published scholarship on augmenting water supplies in the Colorado Basin in the University of Arizona Environmental Law and Policy Journal and climate litigation in the Arizona State Law Journal.  After graduation, he served as a judicial clerk for Justice James P. Beene of the Arizona Supreme Court. Those experiences refined his legal writing, research, and analytical skills and deepened his engagement with Arizona’s environmental and administrative law landscape.

Outside of his practice, Sean is an avid wildlife photographer who finds inspiration in Arizona’s diverse landscapes and ecosystems—an appreciation that continues to inform his professional commitment to sustainable and resilient communities.
