About

Coston, McIsaac & Shea (CM Partners) provides discretionary and non‑discretionary investment management and consulting primarily to individual and high‑net‑worth clients, as well as trusts and organizations. The firm serves a predominantly individual client base and acts as a level‑fee fiduciary when managing client assets.

The firm emphasizes long‑term, asset‑allocation strategies that rely on low‑cost, no‑load mutual funds and select individual stocks with lower volatility and dividend histories, using both fundamental and technical analysis. CM Partners tailors recommendations to each client’s goals and risk tolerance, and directs clients to custody and execute transactions through Charles Schwab as the firm’s recommended broker‑dealer.

A distinctive feature is CM Partners’ close operational and professional affiliation with related firms: an affiliated SEC‑registered adviser and a local CPA practice (Coston & McIsaac CPAs). These relationships — including shared personnel and facilities, movement of accounts from the affiliated adviser into CM Partners, and the availability of accounting and non‑securities advice through the CPA affiliate — reflect an integrated adviser/accounting arrangement that is uncommon among peer team firms.
