About
Castle Rock Financial Planning serves individuals — including high-net-worth clients — as well as trusts and estates, offering personalized financial planning and discretionary portfolio management. Its services cover retirement, tax, estate, insurance, education funding, cash-flow analysis, and implementation support through custodial brokerage accounts.
The firm operates as a fee-only fiduciary and places trades under a limited power of attorney while recommending a qualified custodian for asset custody and execution. Investment programs are built from stocks, bonds, mutual funds, and ETFs and are monitored through regular account reviews and periodic client meetings to track progress against documented goals.
Compared with many peers, Castle Rock is a single-advisor practice led by a principal with advanced professional credentials (CFA, CFP, AIF) and uses fee arrangements beyond a pure percentage-of-assets model, including project-based planning and flat periodic advisory fees that can be tailored to client complexity. The firm does not accept commissions, makes clear that it has constructive custody through automatic fee deduction, and expects clients to retain proxy voting authority rather than voting securities on their behalf.

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.
