Ameriprise has added The Atlantic Group, a 16‑member advisory practice based in Boca Raton, Florida, to its branch channel. The group manages more than $1.6 billion in client assets and brings nine financial advisors and seven support staff.

The Atlantic Group was previously part of Oppenheimer & Co. Inc. The founders, Andrew Lerner and Logan Shalmi, built the practice organically over the past decade and have emphasized a client‑first culture that aligns with Ameriprise’s goal‑based advisory model.

Ameriprise’s Executive Vice President and President of the branch and financial institutions channels, Pat O’Connell, said the addition “embodies the client‑first mindset and forward‑thinking leadership we value at Ameriprise.” Lerner and Shalmi noted that the firm’s advanced planning tools, broad investment product suite, and technology platform will help the new advisors scale their businesses and deepen client relationships.

The move expands Ameriprise’s nationwide advisor network and is expected to enhance revenue generation and client retention by leveraging the firm’s resources to drive additional fee income and asset growth.
