Stifel has recruited ten advisers, including a team that managed more than $3.9 billion, a company spokesman said.

The largest of Stifel's new hires comes from Oppenheimer. The team, known as PearlStreet Investment Management, opened a new office for Stifel in Ada, Mich., a suburb of Grand Rapids. They manage more than $600 million in fee-based client assets and also have an institutional retirement plan practice that is responsible for more than $5 billion in retirement plan assets, of which $3.3 billion was custodied at the firm, according to Stifel.

The recruits were hired by the firm last week. Team members include managing directors Kevin Cusack, Joe Horlings, Susan Rose as well as financial advisers Jim Shuster, Shawn Kersjes and Drew Wilson.

Cusack said in a statement they made the move because of Stifel's technology culture, which he described as "a fit for our Midwestern values."

An Oppenheimer spokeswoman declined to comment on the team's departure.

Cusack is an industry veteran, having started his career at A.G. Edwards in 1984, according to FINRA BrokerCheck records. He later worked for McDonald Investments before joining Oppenheimer in 2003.

Horlings and Rose both started their careers at McDonald in 1992. Shuster joined the industry with Edward Jones in 2003, transitioning to Oppenheimer in 2011.
