Sentinus

Sentinus

Sentinus opened in 2012 as a registered investment advisor in Oak Brook, Illinois. The firm was founded by Trevor M. Ashmun, though details of his prior career or the specific wealth-origin event that seeded the practice remain part of the firm's private client record. The advisory structures itself around comprehensive wealth management for high-net-worth individuals, families, and related entities including private trusts and corporations. Sentinus frames its investment process around portfolio management and integrated estate planning, serving as a fiduciary rather than an asset gatherer. The firm's regulatory filings confirm a broad advisory mandate spanning equities, fixed income, and alternative allocations, with client portfolios shaped by individual risk tolerance and multi-decade wealth-transfer objectives. The geographic base in suburban Chicago anchors a clientele that concentrates in the Midwest, though the firm reports advising entities beyond Illinois. Sentinus operates without publicizing asset totals or headcount — standard for a closely held RIA serving a discreet client base. The firm's Form ADV records indicate a lean advisory team that functions as an outsourced family-office function for clients, coordinating estate attorneys and tax professionals alongside direct portfolio oversight. No formal club memberships, philanthropic vehicles, or adjacent investment partnerships are disclosed. What distinguishes Sentinus is the advisor-as-general-contractor model: estate planning, tax coordination, and investment management all sit under one advisory roof rather than being referred out. For clients, the structural promise is continuity across generations — the RIA persists beyond the liquidity event and doesn't require a family to build its own office infrastructure.
