Current Focus: New Paradigm Institute

Founded as an initiative of the  Romero Institute in 2023, NPI’s mission is to compel full and responsible  Unidentified Aerial Phenomena (UAP) disclosure from governments, companies, and individuals—and to help society prepare for the cultural shifts that verifiable evidence may bring.  Danny Sheehan’s involvement with UFO/UAP advocacy dates back to the Carter administration; NPI renews that commitment to transparency and accountability.

UAP disclosure • government transparency • non-human intelligence • responsible reporting
