About

Joel Isaacson & Co., LLC provides comprehensive wealth management and portfolio management primarily to high net worth individuals and, on occasion, to corporate pension and profit-sharing plans, charitable organizations and corporations. Services described in the brochure include financial planning, continuous tax and estate planning, investment implementation and reporting, and ancillary offerings such as tax preparation, tax compliance consulting, family office services, bill paying, outsourced CFO work and limited trustee services.

The firm favors long-term investment strategies, typically recommending mutual funds, ETFs and private investment funds and providing both discretionary and non‑discretionary advice; it may also retain third‑party managers for portions of client portfolios and monitors those managers on an ongoing basis. JIC discloses routine tax-aware activities (for example, limited trading for tax harvesting or cash needs) and emphasizes continuous monitoring and periodic client reviews rather than frequent trading.

What distinguishes JIC from many peers is its ownership and group affiliation: it is an indirect, wholly owned subsidiary of Focus Financial Partners, LLC (with CD&R and Stone Point investment vehicles as indirect owners), and therefore sits within a network of Focus Partners that includes pension consultants, broker‑dealers, insurance firms and other firms that manage or advise private funds. The brochure also notes the firm’s broader service mix (in‑house tax and outsourced CFO services and trustee work) and participation in Focus-sponsored industry events (which list external law firm participants such as K&L Gates LLP), reflecting operational and referral linkages that are less common among multi‑team advisory firms.
