About
Rainbrook Capital LLC is an independent, state‑registered investment adviser that provides discretionary portfolio management and financial planning to individuals, high‑net‑worth households, and families. The firm also offers qualified retirement plan consulting services for small‑business plan sponsors, including 401(k) plan support.
Rainbrook builds portfolios tailored to each client’s goals, time horizon, risk tolerance, liquidity needs, and tax circumstances and generally follows Modern Portfolio Theory for asset allocation across equities, fixed income, cash and alternatives. Its investment process uses multiple analysis methods — fundamental, technical, bottom‑up and top‑down — and may employ mutual funds, ETFs, individual equities, options, bonds, REITs and commodities, with an effort to limit turnover in taxable accounts.
A distinctive feature relative to many solo independent advisers is Rainbrook’s pension consulting practice: the firm serves as an ERISA Section 3(21) and/or 3(38) fiduciary for plans, prepares investment policy statements, provides discretionary plan‑level advice, performance monitoring, and participant education. The brochure also indicates an early‑stage profile — an initial state registration with no assets under management reported as of March 27, 2026 — while using a major custodian for account custody and institutional servicing features such as block trading.

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.
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.
