About Zenith Economics
An independent economic consulting firm in Los Angeles that measures the economic and fiscal impact of organizations, projects and events.
Built by economists for public scrutiny
Samuel Maury-Holmes founded Zenith Economics in 2024 after leading economic impact work as Practice Lead at Beacon Economics. The firm produces economic, fiscal and social impact studies, each delivered with a designed report, an executive summary and a presentation for the client’s board or council.
We take no sponsored research and have no financial interest in the results we report, so clients can put our numbers in front of legislators, boards and reporters. Recent clients include the Montana Department of Transportation, LACERA, Crowder College and Port San Antonio. Our studies have been covered by Billboard, Texas Public Radio, the San Antonio Report and the Joplin Globe, and cited by the Texas Comptroller of Public Accounts.
Our economists have contributed to more than 100 impact studies over their careers. Two of us, Samuel Maury-Holmes and Johnathan Cahill, are among the 42 economists listed in IMPLAN’s Certified Economist directory. Zenith is a California-certified Small Business. Fees, credentials and selected results are collected on the firm facts page.
