Mariner Independent

The firm provides investment advisory, financial planning, and consulting services to a broad client mix that includes individuals (including high‑net‑worth clients), trusts, charitable organizations, corporations, and employer‑sponsored retirement plans. Services are delivered through independent Investment Adviser Representatives on the Mariner platform and include portfolio management, access to model portfolios and third‑party managers, and stand‑alone planning or tax engagements as requested.

Mariner’s platform supports both firm‑constructed model portfolios (mutual funds and ETFs) and advisor‑level discretionary management, and it supplements adviser capabilities with affiliate investment resources and sub‑advisory relationships (including SEI and AssetMark) and access to alternatives via third‑party marketplaces such as CAIS. For retirement sponsors and participants the firm offers a suite of plan services — including a Pathway DC solution that provides 3(38) fiduciary support and preferred recordkeeper integrations (Empower, T. Rowe Price, Vestwell) — and uses a third‑party participant account management platform to manage held‑away defined contribution participant accounts on a discretionary basis.

Compared with many peers, the firm’s close operational integration with institutional and retirement plan resources is notable: it refers plans to and coordinates with affiliated institutional entities, offers trustee and tax‑related services via related companies, and makes affiliated private funds and manager relationships available to clients. These affiliations give the firm expanded institutional capabilities and access to shared research and product channels, while the brochure also discloses how those relationships and referral arrangements can create conflicts that are managed through disclosure and supervisory procedures.
