Four advisors with U.S. Bancorp Investments, the brokerage unit of U.S. Bank, have jumped ship and joined Ameriprise.

Mark Frederick, Timothy Breitfelder and Larry Eggers formed a team practice in Dubuque, Iowa, with $218 million in assets under management, according to Ameriprise.

"After considering many other firms, we decided to join Ameriprise because of the firm's focus on providing an excellent client experience through financial planning. This focus was a priority for us, but we also wanted to tap into Ameriprise's integrated technology capabilities to help us grow our practice," Frederick said in a statement.

The other advisor, Brooks Staples, joined Ameriprise with $68 million in assets under management. His office is located in New Brighton, Minn.

All four joined the firm's independent channel during the first week of December, Ameriprise said.

U.S. Bancorp Investments has 515 advisors nationwide, while Ameriprise's independent business has approximately 7,700.
