About

MML Investors Services, LLC is a broker‑dealer and SEC‑registered investment adviser that operates as a subsidiary of MassMutual. It provides ongoing financial planning to individuals (including high‑net‑worth clients), business owners, trusts, estates, charitable organizations, and employers, and also offers asset management, wrap and money‑manager programs and educational seminars.

Financial planning engagements are structured as annual, collaborative relationships in which advisers collect detailed client information, use firm‑approved software (including Monte Carlo simulations and automated asset‑allocation tools) to analyze goals, and deliver written recommendations; advisers generally recommend investment categories and strategies rather than making specific product selections and do not have investment discretion as part of the planning engagement. Implementation of recommendations is optional and requires separate brokerage or insurance arrangements, and advisers may receive additional compensation in their capacities as registered representatives or insurance agents when clients choose to implement recommendations.

Noteworthy features in the brochure include the recent addition of a standalone Divorce Planning offering (announced March 2026) and explicit descriptions of estate‑settlement and employer‑sponsored planning programs, which present event‑driven planning services in a defined way. The firm also discloses an extensive history of regulatory and enforcement actions (including SEC and state orders and associated remediation) and details about affiliated‑product distribution and sales‑support compensation arrangements that can create potential conflicts of interest for clients to consider.

Not sure where to start?

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.

Find your advisor

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
