Clift Seferlis
Biography
Clift Seferlis mailed dozens of threatening letters and postcards to Jewish institutions, many referring to Israel, Gaza, or violence against Jewish people. Arrested on June 16, 2025, he pleaded guilty to mailing threats and obstructing religious exercise and was sentenced on March 16, 2026 to thirty-seven months in federal prison.
In a 2010 oral history, Seferlis described his work as a stone carver and architectural historian, learning carving from his father Constantine, and restoring stonework at the Smithsonian.
The 2010 oral-history biography records three years studying architectural history at Drexel, transfer to New York University for design and graduation in 1992. It describes subsequent Smithsonian restoration work and school-group guiding in Washington and New York. These are biographical details, not custody evidence; the subject’s father Constantine is a different person.
