About
No evidence was found supporting the existence of Siena Darrow as a partner or team member at New Enterprise Associates (NEA) on public sources, and she does not appear on NEA's official team page. Additionally, there is no publicly available information linking Siena Darrow to NEA on professional networks or industry references as of November 2025. Because of this, it is not possible to provide a verified professional biography for Siena Darrow at NEA.
NEA is a leading venture capital firm focused on investing in technology and healthcare companies across all stages, with a team of well-documented partners specializing in various sectors. However, Siena Darrow is not listed among them, nor are there records of her prior roles at Johnson & Johnson or her academic credentials in the context of NEA's publicly recognized team members.
If additional information or clarification about Siena Darrow's affiliation with NEA or her current role emerges from authoritative sources, a professional biography can then be provided. For now, there is no substantiated evidence supporting her current partnership at NEA.
