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.
