Alexander Simpson

Senior Vice President

Alex is a Senior Vice President at Cassidy & Associates, where he focuses on the transportation sector. Alex brings a wealth of experience to Cassidy, most recently serving as Senior Counsel on the Senate Committee on Commerce, Science, and Transportation under Chair and Ranking Member Sen. Maria Cantwell (D-WA). In that role, he led oversight of the FAA, TSA, NTSB and the aviation industry, and executed over 25 hearings, including multiple high-profile hearings with airline and manufacturing CEOs, union leaders, DOT Secretaries, and FAA Administrators. Alex maintains close ties with the Senate Commerce and House Transportation & Infrastructure committees.

Notably, as a Committee staffer Alex drafted and negotiated the FAA Reauthorization Act of 2024, one of the most significant bills passed in the 118th Congress. He also worked closely on the Infrastructure Investment and Jobs Act, which included more than $25 billion for airport infrastructure upgrades. 

Prior to his tenure in the Senate, Alex practiced law at the U.S. Department of Transportation and Zuckert, Scoutt, & Rasenberger (now KMA Zuckert), where he helped clients problem-solve aviation issues, including those related to the Essential Air Service Program, airport landing rights (slots), antitrust, air carrier economic authority and fitness, federal preemption, and airport grant assurances. He also served as a judicial law clerk for the Honorable James A. Kenney III of the Appellate Court of Maryland and as a staffer for Congressman (now Senator) Chris Van Hollen (D-MD).

A proud graduate of Kenyon College and the University of Maryland School of Law, Alex lives in Northwest Washington with his wife and three children.
