About

Grattan Financial Strategies provides investment advisory and financial planning services to individuals (including high‑net‑worth clients), pension and profit‑sharing plans, trusts, estates, charitable organizations, and business entities. The firm offers tailored portfolio management, comprehensive or limited financial plans, and hourly consulting for clients who do not meet or do not elect managed‑account services.

GFS delivers both discretionary and non‑discretionary management and generally uses fundamental and technical analysis to support long‑ and short‑term purchases across equities, mutual funds (with a preference for no‑load and load‑waived shares), fixed income, and ETFs. Unusually for firms of its size, a larger share of reported assets is managed on a non‑discretionary basis—about $194.7 million versus $158.0 million in discretionary assets—while accounts are monitored on an ongoing basis.

A number of operational features distinguish the firm from many peers: certain advisory personnel are also registered representatives of an affiliated broker‑dealer and hold insurance licenses, so they may receive commission or 12b‑1 compensation when acting in those capacities (a conflict the brochure discloses and says it will avoid where advisory fees apply). The firm executes trades exclusively through the affiliated broker‑dealer, does not aggregate client orders, occasionally serves as trustee for select trust accounts (resulting in custody), and states it absorbs mutual fund trade costs—practices that affect trade execution, custody reporting, and potential conflicts of interest.
