About
Willenbrock Financial Planning serves individual clients, trusts, estates, and small entities with comprehensive personal financial planning and discretionary investment management. The firm offers separate financial planning engagements billed hourly and an ongoing investment advisory service billed as a percentage of assets under management.
The firm’s investment approach emphasizes broadly diversified, low-cost index funds across domestic and international equities, emerging markets, real estate, and a range of bonds, with low-risk instruments (government securities, CDs, fixed annuities) used to complement portfolios when appropriate. Portfolios are constructed to match clients’ time horizons and risk tolerances, monitored daily, and rebalanced when allocations move beyond a narrow threshold; the firm does not attempt market timing.
Distinctive features include a single-advisor, fee-only model with a small, closely managed client base and no third-party compensation or product sales. The advisor’s long academic career in physics and operational choices—daily account reviews, a tight rebalancing band, and a policy of keeping client accounts separate rather than aggregating trades—differentiate the practice from many peers.

Not sure where to start?
We'll help you think it through – whether you ultimately need an advisor or not.
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.
By using our service, you agree to Warmer's Terms of Service and Advisory Agreement and Privacy Policy. Logos provided by Logo.dev
