About

Tortoise provides discretionary investment management primarily to high‑net‑worth individuals and trusts, with a substantial portion of its clientele made up of professionals in demanding careers. In addition to portfolio management, the firm offers ongoing financial advice on non‑investment matters—such as college and retirement planning, mortgage financing, insurance, charitable giving and estate planning—when clients request those services.

The firm’s investment philosophy emphasizes risk management, a conservative long‑term orientation, and tax efficiency, relying on asset allocation, diversification and periodic rebalancing as primary portfolio drivers. Implementation is largely via ETFs and index‑like mutual funds, and for certain clients Tortoise employs direct indexing through a sub‑adviser as well as tax‑loss harvesting, interval funds and options strategies for hedging or income where appropriate.

Tortoise is a fee‑only fiduciary that treats cash as an asset class included in assets under management and recently changed its fee calculation process to a third‑party performance reporting system that uses trade‑date valuations, which can create minor timing differences with custodian reports. The firm also leaves proxy voting to clients (proxys are sent directly) and will not exercise discretionary authority to purchase cryptocurrencies without explicit client authorization, practices that distinguish its governance and digital‑asset approach from many peers.
