JP Marvel Wealth Management

JP Marvel Wealth Management

John P. Marvel launched the firm in 2007 from Boston, Massachusetts, establishing a registered investment advisor that serves individuals, trusts, and corporations. The practice was built around combining investment advisory services with in-house financial planning and tax strategy, a departure from siloed wealth management models typical of the period. The firm operates with a fiduciary standard, removing commission-based conflicts from its client relationships. The firm manages discretionary portfolios across public equities, fixed income, and third-party alternative strategies. It does not run proprietary fund products. Asset allocation is driven by client-specific liquidity needs and tax situations rather than a house model portfolio. The practice includes direct indexing and tax-loss harvesting for high-net-worth taxable accounts. Client assets are custodied externally, with the firm acting as overlay manager and coordinator across planning, investment, and tax preparation workflows. The office is located in Boston. Team size and total assets under advisement are not publicly disclosed. Unlike multi-family offices that aggregate capital into institutional-quality vehicles, JP Marvel Wealth Management operates as an integrated planning and asset management practice for private clients. The firm has not announced adjacent vehicles such as philanthropic foundations or real-asset arms. Its structural differentiator is the marriage of tax preparation, estate planning, and discretionary portfolio management inside a single fee-only RIA — a configuration that allows tax decisions to inform trading in real time without a separate CPA or broker-dealer intermediary. For a boutique Boston firm, that integration functions as both service model and competitive moat in a market dominated by wirehouses and trust companies.
