SEC-identified person · CIK 1706400 Identifier-verified

Public-company roles (from insider filings)

CompanyCapacity as filedFilings
Acumen Pharmaceuticals, Inc. ABOS Director filed 2023–2026
Passage BIO, Inc. PASG Director filed 2021–2026
Atara Biotherapeutics, Inc. ATRA SVP, Head of Global Commercial filed 2017–2019

All roles under one Commission-assigned identifier - the same person by the SEC's own record, not by name matching. From the SEC's insider-transaction filings (Forms 3, 4 and 5). Every reporting director and officer carries a Commission-assigned identifier (CIK), so these footprints are identifier-verified - no name matching involved. Insiders file when they transact, so dates are filing dates: "last filed" never means "served until". This layer is not yet joined to the nonprofit register - identity joins ship only after independent review.
