About
Prospero Financial Planning is a small independent registered investment adviser that serves individual investors as well as pension and profit‑sharing plans, trusts, estates, charitable organizations, and business entities. The firm provides modular financial planning, ongoing portfolio management (both discretionary and non‑discretionary), and pension consulting tailored to each client’s needs.
Portfolios are constructed using fundamental analysis and a mix of long‑ and short‑term strategies, with ongoing monitoring and rebalancing; the firm primarily recommends mutual funds but also advises on equities, fixed income, options, futures, and partnership interests. It may engage third‑party money managers or model portfolios for portions of accounts and may aggregate related household accounts for fee breakpoint considerations, reflecting a combination of direct management and outsourced solutions.
Noteworthy for its scale—managing roughly $4.5 million across about a dozen client relationships—the firm offers plan‑level pension consulting and participant education, services less commonly provided by firms of this size. The brochure also discloses a prior state regulatory fine for a late questionnaire filing and describes participation in custodial programs that facilitate block trading and access to institutional services.

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
