About
Seneschal Family Office serves high‑net‑worth and individual clients, multi‑household families, and employer‑sponsored retirement plans, providing financial planning, portfolio management, and family office services. The firm operates as a fee‑only advisory, delivering planning deliverables and ongoing investment management across a range of account types, including held‑away qualified accounts and participant‑directed retirement assets.
The firm’s investment work is structured around written Investment Policy Statements, a focus on strategic asset allocation using mutual funds/ETFs and third‑party managers, and periodic portfolio reviews with discretionary trading and rebalancing. Seneschal also employs longer‑term purchase strategies and may use option strategies and independent managers as part of implementing client allocations.
Compared with many peers, Seneschal manages roughly $300 million with a three‑advisor team while offering family office‑style services (including coordinated multi‑household arrangements and limited in‑house tax filing support) that are priced and delivered alongside AUM‑based management. It also provides ERISA 3(38) fiduciary services for retirement plans and relies on a third‑party held‑away platform to view and manage qualified assets — a specialized operational approach that requires client credentialing and involves a split of platform economics.

Not sure where to start?
We'll help you think it through—whether you ultimately need an advisor or not. Warmer helps you compare advisors clearly, so you can choose with confidence.
For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Advisors are independent and may not have reviewed or updated this information. Please review an advisor’s Form ADV and do your own diligence before deciding whether to work with them.
Advisor matching and introductions are provided by FinanceHQ LLC (“FHQ”), a wholly-owned subsidiary of Warmer and an SEC-registered investment advisor. We receive compensation from certain participating advisors for introductions or referrals. This creates a conflict of interest because we have an incentive to recommend advisors who compensate us, including those who pay us more. You pay no fee to use our matching service, and advisor fees are not increased because of a referral or introduction. We do not review the ongoing performance of advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
By using our service, you agree to our Terms of Service and Advisory Agreement, and acknowledge our Privacy Policy. Please review FHQ’s ADV Part 2A and Form CRS. Logos provided by Logo.dev
