About

Long River provides discretionary investment management through separately managed accounts to individuals, high‑net‑worth clients, trusts, foundations, corporations, and certain institutional clients. Portfolios are managed under two primary approaches — a concentrated, high‑conviction equity strategy and an ETF‑based, globally diversified strategy — with allocations tailored to client risk tolerance and goals.

The firm’s investment process is fundamentally oriented, seeking companies at a discount to conservatively estimated intrinsic value and favoring long‑term, tax‑efficient ownership with generally low turnover. It maintains a research library and a mosaic research approach, dynamically shifting between its concentrated equity and ETF strategies and often using Berkshire Hathaway as a U.S. index substitute for cost and private‑equity exposure.

Noteworthy for an independent advisor of its size, the firm provides supplementary annual performance reports and advertises performance results, and it accepts corporate and institutional clients in addition to individual and family accounts. Management is led by the firm’s principal (with attendant key‑person risk disclosed in the brochure), and the firm does not accept commissions or sell commissioned products.

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.
