Clark County Department of Aviation

Rosemary A. Vassiliadis is the Director of Aviation for Clark County, Nevada. The aviation system she leads is anchored by Harry Reid International Airport (LAS), consistently one of North America's top 10 commercial airports, which handled a record 58.4 million passengers in 2024. In addition to directing all operations at LAS, she oversees four general aviation airports in Southern Nevada. She has more than 25 years of experience in aviation leadership.

LAS is not only the gateway to one of the world's premier leisure and convention destination, it is a $35 billion economic engine driving Southern Nevada's primary industry. Recognizing that the airport serves as visitors' first and last look at Las Vegas, Vassiliadis prioritizes efforts to enhance the total customer experience for all travelers. As evidence of the airport's success, it earned top ranking among mega airports in the J.D Power and Associates 2018 North America Airport Satisfaction Study, and most recently ranked #6 in 2024.

The most important obligation of the air travel industry is passenger safety and security. Vassiliadis directed all airport operations in the immediate aftermath of the Sept. 11 attacks and under her leadership, LAS was one of the first airports in the United States to reopen. The airport remains an industry leader in security programs, serving as the site for the Transportation Security Administration's (TSA) first and only Innovation Checkpoint, a unique space dedicated to side-by-side testing and evaluation of emerging security technologies in a live checkpoint environment. Additionally, Vassiliadis serves on the Nevada Homeland Security Commission, having been appointed by four different governors.

Vassiliadis led LAS through the impacts of COVID-19. By adopting new, best practices and implementing innovative strategies, the airport was able to maintain operations and provide a safe and healthy travel experience. With a focus on cost containment and operational efficiency, and in keeping with the latest guidance from public health officials, she led her team through the economic recovery by welcoming back visitors to this world-class destination.

In 2022, she was appointed to the Federal Reserve of San Francisco's Los Angeles Branch Board of Directors. In this role, she offers expert, industry-specific contributions toward the formulation of national monetary and credit policies. She also served on the board of American Association of Airport Executives (AAAE) as a voting member through April of 2024.

Additionally, Vassiliadis served on the board of the U.S. Travel Association, and has played an active role on Capitol Hill, educating and persuading senators, House members, and administration officials on a variety of issues critical to domestic and foreign travel.

Under her direction, LAS has joined the fight against human trafficking. She's worked with law enforcement and human trafficking experts to train and educate airport employees, establish escape opportunities for victims, and elevate awareness of this international tragedy.

Aside from maintaining the highest and most efficient operational standards, Vassiliadis has declared two other major priorities for the department: diversity and community partnership.

Vassiliadis is responsible for an important cultural shift at the Department of Aviation focused on the core belief in the importance of sharing ownership of the airport with the entire community. LAS has taken significant strides in providing business opportunities for local, minority and women-owned businesses. Vassiliadis established a process to inform and support applicants for airport concession request for proposals (RFPs).

For this commitment to community, she and the department have received accolades and awards from the Las Vegas Urban Chamber, Asian American Group, Western Regional Minority Development Council, Girl Scouts of Southern Nevada, and Nevada Broadcasters Association, to name a few. She also partnered with local veterans and military groups and the United Services Organization (USO) to establish airport lounges for the many members of the military who travel through Las Vegas. As a result, each LAS terminal houses a USO lounge.

Department of Aviation employees have embraced the opportunity to support public schools in Clark County, as have many of the local airline, vendor and federal employees. Classroom reading, school supply donations benefitting underprivileged kids, paper airplane contests, and mentoring are just a few of the many ways LAS plays a role in young lives. In recognition of her many contributions, and those of her husband, the Clark County School District in 2017 named a new school Billy & Rosemary Vassiliadis Elementary.

Vassiliadis has also been an advocate for sustainability efforts throughout the department. In recent years, many steps have been taken to reduce the industry's impact on the environment. These measures include replacing more than 10,000 lights with energy-efficient LED lights; shifting to drought-resistant xeriscaping along the airport's roadways; and installing charging stations for electric ground support equipment, as well as customers' vehicles.

Vassiliadis' focus on operational efficiency and financial prudence comes from her educational and professional background. She graduated with a degree in accounting from DePaul University, served as the budget chief for the City of Las Vegas, and was appointed Clark County Director of Finance.

Vassiliadis has been married for more than 40 years, raised two successful children, and is the proud grandmother of a little boy. She's also a fanatic supporter of the Chicago Cubs.
