About
TwentyThree Advisory provides ongoing portfolio management services primarily to high‑net‑worth individuals, creating Investment Policy Statements that document clients’ goals, tax considerations, time horizons and risk tolerances. The firm offers asset allocation, security selection and regular monitoring and delivers services under both discretionary and non‑discretionary arrangements while not participating in wrap fee programs.
The firm’s investment approach relies on fundamental analysis and a long‑term trading horizon, with a focus on equities complemented by mutual funds, ETFs, fixed income, real estate funds (including REITs) and private placements. Client accounts are custodied at Schwab Institutional (the firm requires clients to use that custodian), reviewed at least quarterly, and clients receive monthly account reports from the custodian.
Notably, as of December 2025 the majority of the firm’s assets — $37,466,829 of $41,104,123 — are managed on a non‑discretionary basis, a relatively uncommon arrangement among independent advisers. The firm also maintains a very small, concentrated client roster of high‑net‑worth individuals, discloses no soft‑dollar benefits or third‑party sales compensation, and limits its recommendations to a defined set of investment types.

Not sure where to start?
We'll help you think it through – whether you ultimately need an advisor or not.
Warmer provides personalized recommendations and introductions to independent fiduciary advisors. We do not supervise advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
Each advisor listed on our site is an independent fiduciary responsible for their own advice. Warmer may receive fees from advisors for participation or referrals; these fees are paid by advisors and do not affect the fees clients pay for advisory services.
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. Please review an advisor's Form ADV and do your own diligence before entering into an advisory relationship.
