A PDF hosted on arabellaadvisors.com, “How Arabella Can Help Philanthropists and Impact Investors Close the Racial Wealth Gap,” lists Isaiah Castilla among “Arabella’s Wealth Gap Practice Leaders.” The bio: “Isaiah is a managing director in Arabella's Washington, DC office. Before coming to Arabella, Isaiah was general counsel and secretary for Democracy Fund and Democracy Fund Voice.” It repeats the Bolder Advocacy counsel line and the Musgrove / Sink / Luckett campaign-finance line. Contact block on that PDF includes an Arabella email. This site does not reprint a phone number as a contact for the commentary page.
The PDF is an employer marketing document. It is a primary for the title they gave him on that practice page. It is not a grant ledger. It is not proof that he directed any named client engagement described elsewhere in the same PDF (J.P. Morgan Chase, Oakland Fund for Public Innovation, Bedford Stuyvesant Restoration Corporation, an unnamed Silicon Valley family). Those case studies are not assigned to him unless a source names him on the engagement. None of those case studies in the fetched PDF name him as the lead. The “we influence more than $4B in philanthropic assets annually” line is Arabella’s firm claim. It is not his personal total.
