“With these appointments, we’ve better aligned our talented management team with our businesses, enabling Stifel to continue on a strong growth trajectory.”

As COO, Sliney will be in charge of managing responsible for technology, operations, and platform development.

He has been associated with the company since 2003 under multiple designations including senior vice-president of strategic planning, technology, and operations.

“The growth and success of Stifel’s business over the past two decades would not have been possible without David’s significant contributions.

“Not only has he played a key role in the strategic direction of the firm over the past 20 years, but David has overseen the integration of our acquisitions as well as the development of our technology and back-office systems,” Kruszewski.
