On Engagement.

Inspired by Harpocrates, the ancient guardian of silence, Custos Fidei is governed by principles of discretion and restraint. Engagements arise, as a matter of preference, through confidential introduction via our network of trusted correspondents, including multi-family offices, private banking, trustees, and selected fiduciary advisors. On occasion, we are willing to consider direct approaches — though we reserve, without exception, the right to decline any engagement at our sole discretion and without explanation.
