Connecticut Cambridge Advisors

Founder Bill McMahon anchors the investment committee and remains the primary portfolio manager. The firm has historically operated with a small team, meaning McMahon directly shapes asset-allocation policy and tax-loss harvesting schedules for every household on the platform. No external investment sub-advisor has been disclosed in public filings.

Connecticut Cambridge Advisors charges asset-based advisory fees and does not manufacture proprietary funds. This fee-only, fiduciary structure means it can allocate to third-party vehicles — historically Dimensional Fund Advisors, Vanguard, and PIMCO — without revenue-tiering pressure. The absence of a proprietary product shelf keeps manager selection tied to a client's tax basis, not a profit-and-loss target.

Tax management is the operational center of the firm. The team runs individual municipal-bond ladders attuned to Connecticut and Massachusetts state income-tax rates and has increasingly adopted direct-indexing technology. When a client carries a concentrated equity position, the firm coordinates with estate attorneys and tax counsel on structured diversification plans — sometimes spanning multiple tax years — rather than executing a single large-block sale.
