Flat-fee, SRI/ESG (Socially Responsible Investing/Environmental, Social and Corporate Governance) financial advisors in New York
The right financial advisor for you depends on how you weigh location, expertise, experience, the clients they typically serve, and how they work with you.
If you want your investments to reflect your values, such as environmental care or social justice, you need an advisor who understands the nuances of socially responsible investing (SRI) and environmental, social, and corporate governance (ESG) criteria. Without this expertise, you might end up with portfolios that claim to be responsible but don't align with your priorities.
- Clear impact criteria. Ask how they define and measure the social or environmental impact of investments, not just financial returns.
- Portfolio customization. Confirm they tailor your portfolio to your specific values, rather than applying a generic ESG filter.
- Fee transparency. Flat-fee advisors charge a set rate, so understand exactly what services are included and how fees are structured.
- Ongoing monitoring. Responsible investing requires regular review to ensure holdings continue to meet ESG standards; ask how they handle this process.
Here are top matches to get you started. Review each profile to compare experience, credentials, and approach.

We'll help you think it through—whether you ultimately need an advisor or not. Warmer helps you compare advisors clearly, so you can choose with confidence.
For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Advisors are independent and may not have reviewed or updated this information. Please review an advisor’s Form ADV and do your own diligence before deciding whether to work with them.
Advisor matching and introductions are provided by FinanceHQ LLC (“FHQ”), a wholly-owned subsidiary of Warmer and an SEC-registered investment advisor. We receive compensation from certain participating advisors for introductions or referrals. This creates a conflict of interest because we have an incentive to recommend advisors who compensate us, including those who pay us more. You pay no fee to use our matching service, and advisor fees are not increased because of a referral or introduction. We do not review the ongoing performance of advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
By using our service, you agree to our Terms of Service and Advisory Agreement, and acknowledge our Privacy Policy. Please review FHQ’s ADV Part 2A and Form CRS. Logos provided by Logo.dev
