Plimsoll Financial Planning, LLC

Plimsoll Financial Planning is a fee-only, independent advisory firm that serves individual (including high-net-worth) clients and businesses, offering ongoing financial planning, a combined planning-plus-investing service, and limited-scope fixed-fee projects for one-off needs. The firm operates as a solo adviser and does not accept commissions or transaction-based compensation.

The firm uses a goals-based planning process—collecting client data, analyzing the financial picture, presenting and implementing recommendations, and monitoring results—with a structured onboarding of multiple meetings followed by at least three reviews per year. When investment management is part of the engagement, Plimsoll implements portfolios through third‑party outside managers, assisting clients with manager selection, questionnaire completion, and ongoing monitoring rather than providing standalone investment management.

Plimsoll’s business model is notable for its reliance on flat annual planning and bundled planning-plus-investing fees and fixed-fee project offerings instead of the percentage-of-AUM billing common among peers, and it offers discounted planning pricing for medical residents and other emerging professionals. The firm manages a modest amount of assets for a small client roster (roughly $6.3 million across 13 clients), commonly recommends Charles Schwab for custody, and discloses that some outside managers may debit and remit Plimsoll’s fees—arrangements the firm identifies as potential conflicts of interest.
