Democratic Congressional Campaign Committee Chairman Chris Van Hollen (Md.) on Friday announced three senior-level staff appointments at the committee.

Jennifer Crider has been named deputy executive director, Jennifer Pihlaja will serve as incumbent retention director, and Marlon Marshall will be the new national field director.

“They know what it takes to win tough campaigns and have the skill and savvy to get it done,— Van Hollen said. “Their experience in House battleground states will be invaluable to our Members and candidates this cycle.—

Crider was communications director at the committee in the 2008 cycle and is a former senior aide to Speaker Nancy Pelosi (D-Calif.). She will also continue to serve as an adviser to Pelosi in her new role.

Pihlaja will serve as director of incumbent retention and will lead the effort to protect more than 50 threatened Democratic incumbents this cycle.

Pihlaja was Midwest regional political director during the 2008 cycle. Before that, she served in the political department at EMILY’s List.

Marshall comes to the DCCC after working at the U.S. State Department and serving on President Barack Obama’s transition team. In 2008, he directed Obama’s campaign in Missouri. Before that, he was field director for then-Sen. Hillary Rodham Clinton’s (D-N.Y.) presidential campaign in Nevada, Ohio and Indiana.
