Patricia Mulroy grew up on an Air Force base in Germany and first came to Las Vegas as a college student. Currently, she oversees the operations of the Las Vegas Valley Water District, which provides water to more than one-million customers, and the Southern Nevada Water Authority, which is responsible for acquiring, treating and delivering water to local agencies that collectively serve approximately two-million residents and nearly 40 million annual visitors. Mulroy joined the Water District more than 20 years ago and began serving as its general manager in 1989. She was a principal architect of the SNWA, which has served as a model for other Western water agencies since its creation in 1991.

As general manager of one of the country's most progressive water agencies, Mulroy is exceptionally active in regional and national water issues. She serves on the Board of Directors of the Association of Metropolitan Water Agencies and the National Water Resources Association, and is a member of the American Water Works Association. Additionally, she was the original chairperson of the Western Urban Water Coalition and served on the Colorado River Water Users Association's board of directors.

A resident of Southern Nevada for more than three decades, Mulroy is equally active in the community. She chairs the University of Nevada, Las Vegas College of Sciences Advisory Board, and has served on the Nevada Public Radio board of directors. Patricia Mulroy was the 2008 recipient of the UNLV College of Sciences Math and Science Education Achievement Award. Mulroy is also actively involved with the Diocese of Las Vegas and Bishop Gorman High School. Her honors include National Jewish Medical and Research Center's Humanitarian Award and the University and Community College System of Nevada Board of Regents Distinguished Nevadan Award. She is a graduate of UNLV (B.A., M.A., German Literature).

Mulroy is also the driving force behind the creation of the Springs Preserve, a 180-acre cultural and historical attraction designed to commemorate Las Vegas dynamic history and to provide a vision for a sustainable future. Known as the birthplace of Las Vegas, the site of the Springs Preserve was once home to bubbling springs that were a source of water for Native Americans living here thousands of years ago. It also sustained travelers of the Old Spanish Trail and Mormons who came to settle the West.

Mulroy served as special assistant to the Clark County Manager and as Clark County Justice Court Administrator before joining the district. She and her husband, Robert, have two children.
