## About

Marble Harbor Investment Counsel was founded in Boston in 2005 as a registered investment advisor focused on discretionary portfolio management for individuals, trusts, estates, foundations, and charitable organizations. The firm operates without the conflicts of a broker-dealer model, charging fees based on assets under management rather than commissions. The firm manages concentrated portfolios spanning public equities, fixed-income securities, and cash equivalents. Its approach centers on direct security selection rather than fund-of-funds allocation, targeting long-term capital appreciation alongside income generation. Marble Harbor constructs individual bond ladders and equity portfolios weighted toward high-quality, dividend-paying companies. The geographic focus is domestic US markets, with a client base concentrated in New England. The firm has not publicly disclosed participation in venture capital, private equity, hedge funds, or real asset co-investments. Marble Harbor maintains a single office in Boston and has not publicly disclosed its total assets under management or professional headcount. No adjacent vehicles — such as philanthropic foundations, real-asset arms, or club deal networks — have been identified. There is no public record of a recent capital raise, spinout, or restructuring. The firm operates below the radar of industry databases, which limits independent verification of its scale, team composition, or recent investment activity. Marble Harbor's structural differentiator is its fiduciary-only posture as a registered investment advisor with no proprietary products, no broker-dealer affiliation, and no transaction-based compensation. This architecture eliminates the incentive conflicts common at larger wealth management platforms. For allocators evaluating the New England wealth advisory landscape, the firm represents a low-profile fiduciary shop in a market dominated by national platforms and bank-owned trust departments — though the lack of public disclosure around AUM, team credentials, and investment track record makes independent due diligence unusually dependent on direct engagement.

## Questions

### Is Marble Harbor Investment Counsel structured as a fiduciary?

Yes. Marble Harbor is registered as an investment advisor (RIA) with the SEC, which legally obligates the firm to act as a fiduciary for its clients. This means it must put client interests ahead of its own, avoid conflicts of interest, and disclose any potential conflicts that cannot be eliminated. Unlike broker-dealers that operate under a suitability standard, Marble Harbor's fee-only RIA structure aligns its compensation with portfolio performance rather than product sales.

### How does Marble Harbor charge for its services?

Marble Harbor operates on a fee-only basis, charging clients a percentage of assets under management. This compensation model eliminates the commissions and revenue-sharing arrangements that create conflicts at broker-dealer firms. Fee-only RIAs like Marble Harbor have a direct economic incentive to grow client portfolios, aligning advisor and client interests. The firm's Form ADV, which all RIAs must file with the SEC, details its specific fee schedule.
