Posted June 12, 2026

Overland Park-based Mariner announced it has expanded its presence in Florida by acquiring Atlantic Wealth Partners, a firm with about $218 million in assets.

Based in Jupiter, Florida, Atlantic Wealth Partners specializes in practice around serving first responders. The firm has built relationships with local police, fire rescue and emergency responders throughout Palm Beach and Martin counties.

Atlantic Wealth Partners was founded in 2017 by Steve Olson.

“Joining Mariner allows us to continue serving those clients while expanding the resources and capabilities available to them. We believe Mariner’s commitment to first responders makes them a strong fit for our team and the people we serve,” Olson said in a release.

Through Mariner’s subsidiary Mariner Institutional, the firm advises approximately $35 billion in assets across 256 retirement plans serving police, fire and public safety personnel. Mariner has also continued investing in resources dedicated to these communities, including the recent addition of Steve Callaghan, a former NYPD Bomb Technician and U.S. Navy veteran, as a senior wealth consultant focused on supporting first responders and their families.

“Atlantic Wealth Partners has earned trust by understanding those realities and building lasting relationships within the communities they serve,” Marty Bicknell, Mariner president and CEO, said in the release. “Their addition strengthens an important area of focus for Mariner and aligns with our purpose to positively impact the lives of many. Together, we will continue investing in the resources and expertise designed to help first responder families pursue their long-term financial goals.”
