Mariner Portfolio holdings
Mariner is a wealth management firm that Marty Bicknell, its chief executive, started in 2006 when he left a large national firm after 16 years. Each adviser can call on in-house specialists in taxes, estate planning and insurance, and the firm works with executives, business owners and professional athletes. Portfolios are built from individual stocks, bonds and funds, using both active and passive strategies, with some money placed with outside managers. Its first major acquisition outside Kansas City came in 2012 and opened the door to investment banking, and in 2018 it brought its sub-brands under a single Mariner identity. Bicknell controls the holding companies that own it, alongside investors affiliated with Leonard Green & Partners.
