About
Black Brook Financial Planning is a small independent registered investment adviser that provides advisory and discretionary investment management and financial planning to individuals, trusts, charitable organizations and corporations. The firm's brochure reports it managed approximately $37.8 million in discretionary client assets as of December 31, 2025 and it typically works with clients saving for retirement or managing retirement income.
The firm uses a conservative, long‑term, value‑oriented asset allocation approach tailored to each client's stated risk tolerance, employing mutual funds, ETFs, individual stocks, bond funds, municipal and corporate bonds, CDs and treasuries. It generally accepts discretionary authority after detailed client discussions, performs account reviews at least quarterly, and uses Charles Schwab for custody and research while drawing on third‑party market publications for analysis.
What is distinctive relative to many peers is that the firm advises and provides portfolio management to charitable organizations and to corporate/institutional clients, and the principal maintains external financial roles (including CFO responsibilities and a treasurer role at a nonprofit) that have led to circumstances where the adviser may have custody when acting in an officer capacity. The firm does not accept commissions or performance‑based fees, does not aggregate trades due to low trading volume, and offers flexible billing arrangements (hourly, flat fee, or percentage of assets) while working with clients who may not meet a formal account minimum.

Forms ADV
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
