About

Mariner serves a broad mix of clients — individuals (including high‑net‑worth households), pension and profit‑sharing plans, trusts, estates, charitable organizations, corporations and private funds — through investment management, financial planning and reporting, retirement plan consulting, and access to pooled vehicles and third‑party managers. The firm also offers coordinated tax services, Core Family Office (CFO) services and employer financial‑wellness tools in addition to traditional portfolio management.

The firm generally implements discretionary, customized portfolios overseen by an Investment Committee and supported by an internal portfolio management team, combining in‑house research with allocations to third‑party managers and platforms (including CAIS access and SEI sub‑advised models). Its strategies span equity and fixed income mandates as well as alternatives, structured notes, options, direct indexing and digital assets, and it provides ERISA 3(38) retirement plan solutions such as the Pathway DC program.

What is less common for a firm of this enterprise scale is the depth of tax and accounting integration: Mariner maintains CPAs and enrolled agents, provides stand‑alone and coordinated tax compliance, planning and preparation, and is affiliated with a specialty tax services entity. The brochure also highlights administrative CFO capabilities (including bill payment and platform administrator authority) and a Financial Wellness Platform for employer clients — operational offerings that are relatively atypical among large advisory enterprises.

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
