About

Bona Fide Finance works primarily with individual clients, including some high-net-worth households, offering comprehensive financial planning, ongoing subscription-based planning, investment advisory, and retirement plan consulting. The firm operates with two advisors and manages roughly $15.7 million in client assets across about 51 client relationships.

The firm combines fee-based planning (fixed-fee projects, hourly engagements, and an ongoing monthly planning service) with discretionary portfolio management, typically implementing passive, asset-allocation-based strategies and using outside managers such as Betterment Advisor Solutions and Dimensional Fund Advisors. Clients are provided ongoing monitoring and planning tools (including RightCapital), and planning work explicitly integrates cash flow, tax, college, retirement, and student-loan considerations.

What distinguishes this firm from many peers is a formal affiliation with a separate tax business (Magni Tax Experts), with the firm’s owner dedicating a material portion of time to that tax practice and disclosed referral arrangements that may create conflicts of interest. The firm also recently added paid educational seminars to its services, reports all assets as discretionary (about $15.7M and $0 non-discretionary as of December 31, 2025), and lists specialized credentials and services—including enrolled-agent tax capability, a Certified Student Loan Professional designation, and access to private fund/REIT offerings for accredited investors—that are less common among similar small advisory firms.

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.
