Top 10 Best Financial Advisors in the US brings together five large wealth-management firms plus five highly ranked individual advisors and teams. The 2026 list can help wealthy UK readers compare US-based investment management. It also covers family-office support, tax planning and cross-border expertise. However, rankings are only a starting point. Fees, regulation, service scope and suitability still require careful checking.
The firms and advisors come from the supplied 2026 Forbes and Barron’s information. SHOOK Research developed the Forbes ranking. Its assessment used assets under management, revenue, client retention and compliance records. It also considered credentials, experience, client impact, best-practice reviews, interviews and firm nominations.
Key Update:
- Forbes’ 2026 America’s Top Wealth Advisors ranking covers 250 advisors. Together, they oversee roughly $2.4 trillion in combined assets.
- The supplied institutional list includes Fisher Investments, Mercer Advisors, Morgan Stanley Private Wealth Management, Mariner Wealth Advisors and Edelman Financial Engines.
- Minimum account sizes differ sharply. The supplied data shows no stated minimum for Jason Katz and $100 million for Lyon Polk.
- Rankings do not measure future investment performance. Therefore, they should not be treated as personal recommendations.
What defines the Top 10 Best Financial Advisors in the US?
The Top 10 Best Financial Advisors in the US are not chosen only by investment returns. Instead, authoritative rankings assess asset scale, client relationships and compliance history. They also examine adviser experience, team structure and the quality of financial planning delivered to clients.
Forbes’ 2026 ranking used data available on 30 June 2025. It was published in April 2026. SHOOK Research combined quantitative and qualitative assessments. These included in-person, virtual and telephone due-diligence meetings. Investment performance was excluded because client goals, risk tolerance and audited performance reporting vary.
That difference matters to a UK investor. A large US team may offer impressive resources. However, it may not understand UK tax residence, currency exposure, pension rules or reporting duties. The practical test is simple: can the adviser explain those boundaries before any money moves?
Which five firms lead the institutional group?
The leading institutional names serve different client groups. Some focus on independent fee-based advice. Others combine private banking, brokerage, workplace retirement services and specialist planning within one corporate structure.
Fisher Investments
Fisher Investments is one of the largest independent fee-only Registered Investment Advisors in the United States. The supplied information places its assets under management above $200 billion. Those assets cover individual and institutional clients.
Its stated strength is custom top-down macroeconomic portfolio scaling. As a result, the approach may suit clients who want a defined investment framework. Still, prospective clients should ask how portfolios change. They should also ask how tax consequences are managed and which services the quoted fee includes.
Mercer Advisors
Mercer Advisors is routinely ranked as Barron’s number-one Registered Investment Advisor firm in the supplied information. Its main distinction is integrated planning. The service combines portfolio management with tax filing, estate planning and corporate benefits support.
This model can reduce the need to coordinate several unrelated providers. Nevertheless, clients should check who performs the legal and tax work. The work may be completed directly, through affiliated professionals or by external specialists.
Morgan Stanley Private Wealth Management
Morgan Stanley Private Wealth Management is a major Wall Street wealth-management institution. It serves ultra-high-net-worth individuals. The firm appears repeatedly in the supplied Forbes ranking. Its listed advisors work with clients in Greenwich, Palm Beach, New York, Menlo Park and other major US markets.
Its scale can support complex domestic and international asset structures. On the other hand, the client experience may depend on the specific team. Minimum account size and the assigned professionals also matter.
Mariner Wealth Advisors
Mariner Wealth Advisors is known for comprehensive wealth services. These include in-house CPA tax advisory and business succession planning. Its model targets business owners and affluent families whose investments connect closely with tax, ownership and exit planning.
For example, a founder preparing to sell a company may need portfolio construction, tax-loss harvesting and succession advice together. A useful meeting question is whether the team has handled similar liquidity events. Also ask how responsibilities are divided among its professionals.
Edelman Financial Engines
Edelman Financial Engines is described in the supplied data as the nation’s largest independent wealth-management firm by client base. It connects workplace retirement planning with personalised wealth forecasting. Standard 401(k) arrangements are included in that positioning.
This model may suit employees moving from workplace savings to a wider retirement plan. The key comparison is service depth. A mass-market retirement relationship may not offer the same family-office support as a private-wealth team.
Which five individual advisors stand out?
The supplied individual-advisor list highlights five leaders linked to large private-capital mandates. Their specialisms include multigenerational wealth transfers and corporate cash management. They also cover liquidity events and philanthropic planning.
| Advisor | Firm and location | Reported focus |
|---|---|---|
| Jeff Erdmann | Merrill Private Wealth Management, Greenwich, Connecticut | Multigenerational wealth transitions and institutional-level asset design |
| Richard Saperstein | Treasury Partners, New York | Corporate cash management and fixed-income portfolios |
| Robert Skinner II | IEQ Capital, Foster City, California | Technology executives and venture-capital clients |
| Ron Vinder | Morgan Stanley Private Wealth Management, New York | Liquidity events, IPO positioning and corporate executives |
| Jason Katz | UBS Private Wealth Management, New York | Family-office services, alternatives and philanthropic legacy planning |
Jeff Erdmann
Jeff Erdmann is based at Merrill Private Wealth Management in Greenwich, Connecticut. He ranks number one overall in the supplied 2026 Forbes data. His team’s stated expertise includes multigenerational wealth transitions and institutional-grade asset design.
The supplied Forbes table reports a $2.5 million minimum account size. It also lists $17.1 billion in team-custodied assets. Typical relationships range from $20 million to $500 million.
Richard Saperstein
Richard Saperstein of Treasury Partners in New York is consistently placed near the top of Barron’s Top 100 Financial Advisors. That position appears in the supplied information. His focus is corporate cash management and fixed-income portfolios.
As a result, his approach may interest companies managing substantial liquidity. Businesses should still examine the team’s cash-management process. They should also review its approach to duration risk and credit exposure.
Robert Skinner II
Robert Skinner II leads IEQ Capital in Foster City, California. The supplied Forbes data reports $41.7 billion in team-custodied assets. His team serves technology executives and venture-capital clients.
Those clients may hold concentrated equity, private investments and irregular liquidity. Consequently, ordinary portfolio advice may not address their full situation. The team’s ability to coordinate these exposures deserves close attention.
Ron Vinder
Ron Vinder works with Morgan Stanley Private Wealth Management in New York. His stated specialisms include liquidity events, IPO positioning and corporate executives. The supplied Forbes table lists a $20 million minimum account size.
It also reports $8.9 billion in team-custodied assets. Clients should ask how the team manages restricted shares, trading windows and post-IPO diversification. These details can affect the practical value of the relationship.
Jason Katz
Jason Katz is associated with UBS Private Wealth Management in New York. He is highly ranked by Barron’s in the supplied data. His focus includes customised family-office services, alternative investments and philanthropic legacy planning.
The supplied Forbes table records a $0 minimum account size. However, prospective clients should confirm the current team policy directly. Minimums can vary by service, client type and office.
How do the firms compare on client fit?
The Top 10 Best Financial Advisors in the US serve different wealth bands. Therefore, firm size alone does not determine suitability. This is especially true for a UK-based client who needs advice across two regulatory or tax environments.
| Firm or advisor | Category | Indicative minimum in supplied data | Best known for |
|---|---|---|---|
| Fisher Investments | Independent RIA | Typically $500,000+ | Top-down macroeconomic portfolio scaling |
| Mercer Advisors | Independent RIA | $500,000–$1 million+ | Integrated tax, legal and investment planning |
| Jeff Erdmann | Private wealth management | Generally $10 million+ | Institutional-grade family-office capabilities |
| Morgan Stanley Private Wealth Management | Broker-dealer and RIA | Varies from $2 million to $10 million+ | Complex domestic and cross-border structures |
| Mariner Wealth Advisors | Independent RIA | Varies by service tier | Tax-loss harvesting and CPA consulting |
These figures are indicative rather than contractual. Account minimums can change by office or team. Eligibility rules and available services may change as well. UK readers should confirm whether advice is available to UK residents. They should also check whether the adviser understands their reporting responsibilities.
What fees and hidden costs should you check?
Most top-tier advisers charge an assets-under-management fee. The rate often starts near 1.00% each year on the first $1 million. It may decline towards 0.50% or below as assets reach higher multi-million-pound or multi-million-dollar tiers. Exact pricing depends on the firm, service package and account size.
For example, a 1.00% annual fee on $1 million equals $10,000 before other costs. This calculation shows why the fee schedule becomes more important as wealth increases. Ask whether the percentage covers planning, custody, tax coordination, private-market access and family-office administration.
- AUM fee: This is an ongoing percentage charged against managed assets. Confirm whether cash and externally held investments are included.
- Platform or custodian fee: Separate charges may come from custodians such as Charles Schwab or Fidelity. These firms hold the assets.
- Fund expense ratio: Mutual funds and alternative vehicles may carry internal costs. Those costs come directly from the investment.
- Transaction or product charges: Some investment products involve dealing costs, spreads or other expenses.
- Tax and legal fees: Integrated planning does not always include tax filing or legal execution. Additional charges may apply.
Fiduciary status also deserves a precise question. Generally, a fiduciary must act in the client’s best interest. However, the duty’s scope should be confirmed in writing. The same applies to the services covered.
The US Forbes wealth-advisor ranking can support initial research. Nevertheless, it is not an endorsement. It also cannot guarantee investment results.
How should UK investors screen a US advisor?
Begin with cross-border questions instead of a performance conversation. A US adviser may be excellent for a US taxpayer. Yet the same adviser may be less suitable for a UK resident with pensions, trusts, offshore assets or sterling-based spending needs.
- Ask whether the team accepts UK-resident clients. Confirm which regulated entity would provide the service.
- Request the complete fee schedule. Include custody, fund expenses, planning and tax-related charges.
- Confirm how dollar portfolios are managed against sterling liabilities and future spending.
- Check who handles UK tax coordination. Also ask whether the adviser works with a qualified UK professional.
- Review regulatory disclosures, disciplinary history, ownership structure and the complaint process.
- Request written details about minimums, investment restrictions, withdrawal terms and service frequency.
A busy executive may have only 45 minutes for an introductory meeting. In that situation, request the documents before the call. Early transparency can reveal more than a polished presentation about market outlooks.
Common mistakes when using rankings
Rankings can narrow a long search. However, they cannot measure the quality of every client relationship. The supplied SHOOK disclaimer says that rankings are opinions for informational purposes. It also states that they do not indicate future performance or represent every client’s experience.
- Choosing a name because of rank alone instead of checking team availability.
- Confusing team-custodied assets with the adviser’s personal investment performance.
- Ignoring currency risk when future spending will be in pounds.
- Assuming tax, legal or family-office services are automatically included.
- Failing to distinguish fee-only advice from broader brokerage or product-based services.
- Transferring assets before reviewing custody arrangements and written terms.
One supplied Forbes table shows why scale needs context. Mark Curtis is listed with $484 billion in team-custodied assets. Jeff Erdmann is listed with $17.1 billion. These figures describe team assets under custody. They do not promise that one team will produce better returns than another.
Frequently asked questions
Who is ranked number one in the supplied 2026 list?
Jeff Erdmann of Merrill Private Wealth Management in Greenwich, Connecticut, is listed as number one overall in the supplied Forbes data.
Are these advisors suitable for UK residents?
Suitability depends on residency, tax status, currency needs and service availability. Confirm cross-border capability and obtain UK-specific tax advice before proceeding.
Does a high ranking guarantee strong investment returns?
No. SHOOK Research says investment performance is not a ranking criterion. Past results also do not predict future outcomes.
What minimum investment might be required?
The supplied figures range from around $500,000 for some independent firms to $100 million for Lyon Polk. Each team sets its own current requirements.
What is the difference between an RIA and a private bank?
An RIA mainly provides investment advice and planning. By contrast, a private bank may combine wealth management with lending, banking and wider financial services.
How can investors compare adviser fees fairly?
Compare the total annual cost rather than the AUM percentage alone. Include custody charges, fund expenses, planning fees, transaction costs and tax or legal work.
Is Fisher Investments independent?
The supplied information describes Fisher Investments as a large independent fee-only Registered Investment Advisor. It serves individual and institutional clients.

Choosing with evidence, not headlines
The Top 10 Best Financial Advisors in the US offer a useful shortlist of firms and teams with substantial resources. Even so, the strongest choice depends on regulatory position, planning depth, communication style and total cost. Cross-border tax and spending circumstances matter too.
Before appointing anyone, verify the current ranking, account minimum, fee schedule and regulatory disclosures. For a UK investor, a clear cross-border plan is more valuable than a famous name alone.
