Boston's best financial advisors, ranked: 9 firms to know in 2026

Boston has been a money management town since the first mutual funds launched here a century ago, and the competition for your portfolio is just as dense today. Dozens of firms within a few blocks of the Financial District manage billions for everyone from young professionals to old New England families.

But "best" is slippery. Barron's, Forbes and SmartAsset all publish rankings, and they measure different things: assets under management, revenue, quality of practice, clients per advisor. None of them measure whether your investments will actually do well.

So instead of inventing our own league table, we compared the major 2026 rankings and picked nine firms that consistently stand out, ordered by how often and how highly they place. Here's what we found, plus how to read any "best advisors" list with healthy skepticism.

1. GW&K Investment Management

The Boston-headquartered firm at 222 Berkeley Street took the No. 1 spot in SmartAsset's Boston ranking, updated May 28, 2026. SmartAsset reports $52.8 billion in assets under management and 63 advisors. GW&K is fee-only and serves high-net-worth individuals alongside institutions, retirement plans and government entities, with specialties in municipal bonds and global equities. Account minimums vary by program.

2. Focus Partners Wealth (formerly The Colony Group)

If you knew The Colony Group, update your contacts: the Boston-rooted firm became Focus Partners Wealth in January 2025, and its March 2025 regulatory filing still listed One Boston Place as its principal office. The national organization now reports $181.8 billion in total client assets and says it ranked No. 6 among Barron's 2026 Mega Firms. It absorbed roughly $35 billion more when Kovitz joined effective January 1, 2026. Services run from investment management to estate, tax and philanthropic planning, with negotiable fees reported up to 1.25%.

3. Cerity Partners

New York-headquartered Cerity made a serious Boston move when it merged with local firm Prio Wealth in January 2025, adding $4.1 billion in assets. The firm says it held its No. 8 spot in Barron's 2026 Mega RIA category and announced three more mergers worth about $2.1 billion on October 1, 2026. It targets high-net-worth families with a $2 million investment minimum, and because partner commissions are possible, "fee-based" is the more accurate label.

4. Loring, Wolcott & Coolidge Fiduciary Advisors

A Boston institution at 230 Congress Street, LWC ranks No. 4 on SmartAsset's Boston list with a reported $12.8 billion in assets and just 13 advisors, an unusually high-touch ratio. It's a fee-only multifamily office handling estate settlement, tax preparation and philanthropy for multigenerational wealth, and its Sustainability Group is a draw for values-driven investors. Minimum: $2 million.

5. SCS Financial / SCS Capital Management

SCS, at 888 Boylston Street, is No. 5 in SmartAsset's Boston ranking with a reported $48.7 billion in assets and 99 advisors. It serves ultra-high-net-worth families, sovereign wealth funds and foreign institutions, with access to private equity and hedge fund strategies. The catch: the general minimum is $25 million. SmartAsset calls it fee-only, though it notes the parent company owns broker-dealers, an affiliation worth asking about.

6. Modera Wealth Management

Modera is headquartered in Westwood, New Jersey (not Westwood, Mass.), but its Boston office is significant enough that its new CIO works from here. The firm reports $17.5 billion in client assets as of December 31, 2025 and says it climbed to No. 37 on Barron's 2026 Top 100 RIA Firms list from No. 40. It's fee-only with no minimum account size, though its March 2026 fee brochure shows 1% on the first $2 million and a $3,000 quarterly minimum fee. In July 2026 it shuffled its C-suite, naming Gaurav Mallik as CIO.

7. Winthrop Wealth

Headquartered at 109 State Street, Winthrop ranks No. 6 on SmartAsset's Boston list with a reported $3.1 billion in assets and 25 advisors. It works with families, business owners, trusts and retirement plans, and notably has no set firm minimum, making it one of the more accessible names on this list. It's fee-based, with advisory fees reported between 0.30% and 2.00% annually.

8. Crestwood Advisors

Crestwood, at One Liberty Square, holds No. 10 in SmartAsset's Boston ranking with a reported $8 billion in assets, 56 advisors, a $1 million minimum and a fee-only model. It also announced a spot on Barron's 2026 Top 100 RIA Firms list in September 2026; its verified numerical rank was No. 74 in 2025, up from No. 81 the year before.

9. Fidelity Wealth Management

The giant in the room. Fidelity's advisory program, run through Strategic Advisers LLC at 155 Seaport Boulevard, offers dedicated-advisor planning to households with $500,000 in eligible Fidelity accounts, with annual advisory fees of 0.50% to 1.50%. It's not an independent fee-only RIA, it's an advisory program inside an affiliated financial services group, but for Bostonians already in the Fidelity ecosystem, it's the lowest-friction option on this list. One 2026 note from its program brochure: BlackRock Diversified Income Portfolio accounts are expected to close by year-end.

What about individual advisors?

Forbes ranks people, not firms, in its 2026 Best-in-State Wealth Advisors list, published April 7, 2026. Boston names include Justin Glucksman of UBS Private Wealth Management, ranked No. 14 in the Massachusetts-Boston Private Wealth category, and Geoffrey Soper of Merrill, who made the 2026 list after ranking No. 33 in the High Net Worth category in 2025.

How to read any "best advisors" list

A few things worth knowing before you treat any ranking as gospel:

• Rankings measure practices, not performance. Barron's methodology weighs assets, revenue and quality-of-practice factors from surveys firms fill out themselves. SmartAsset weighs AUM, client counts and firm age. Neither predicts your returns.
• Categories aren't comparable. Barron's Mega RIA category is for firms managing more than $120 billion, so a No. 8 there and a No. 37 on the broader list aren't on the same scale.
• Commercial relationships exist. SmartAsset earns lead-referral fees from advisors, though it says business relationships don't affect rankings. Several exact ranks above come from firms' own press releases about third-party awards, and we've labeled those sources accordingly.
• Fee-only doesn't mean conflict-free. An assets-under-management fee still rewards gathering assets, something Modera discloses plainly. The SEC's guidance calls for ongoing conflict identification, not just disclosure checkboxes.
• Ask which hat they're wearing. Investment advisers owe a fiduciary duty in the advisory relationship; brokers making retail recommendations fall under Regulation Best Interest. The SEC's standards bulletin explains how the two differ, and dual-registered advisors can wear both hats.

One name you won't see ranked: Boston Private. SVB acquired it back in July 2021, and the legacy now lives on as SVB Wealth, which still lists a 53 State Street address in its March 2026 filings.
