Mariner Advisor Network

What Mariner Advisor Network does

Mariner Advisor Network was a financial advisor firm operating as a business unit of Mariner Wealth Advisors, headquartered in Overland Park, Kansas. Founded in 2006, the firm provided a platform enabling independent financial advisors to deliver wealth management, financial planning, and business consulting services to high and ultra-high net worth clients while maintaining practice autonomy. The network aggregated 367 financial advisors managing approximately $31 billion in client assets, generating revenue through an AUM-based platform services model typical of RIA aggregator structures.

The company's go-to-market was anchored on enterprise field sales relationships with independent advisors seeking scale, infrastructure, and custody support without surrendering autonomy. Distribution relied on industry events, professional networks, and referrals within the advisor community. Underlying technology, proprietary features, and AI/ML capabilities were not disclosed in available sources; technology delivery appears to have leveraged standard RIA platform infrastructure rather than differentiated in-house systems.

In April 2026, LPL Financial, in partnership with Private Advisor Group, acquired Mariner Advisor Network in a transaction described as one of the largest M&A deals in the RIA sector. The deal split the advisor base: 223 advisors remained directly affiliated with LPL, while 144 hybrid advisors transitioned to Private Advisor Group's hybrid RIA model. Following this transaction, Mariner Advisor Network ceased standalone operations, having been absorbed into the combined LPL/PAG platform. The divestiture allowed Mariner Wealth Advisors to focus on its pure RIA strategy, while LPL captured additional custody and clearing economics from advisors already within its broader ecosystem.
