Q: Passage: In 2007 then House Speaker Nancy Pelosi (D-Calif.) appointed Daniel P. Beard of Maryland as CAO. She tasked him to carrying out her Green the Capitol initiative, a move that would later prove not too popular with some Congressional Members. Beard also restructured divisions within CAO that handled such administrative functions as House payroll and benefits.-In July 2010 he handed the reins of the position over to Dan Strodel of Virginia, who prior to becoming CAO served as a senior adviser on the House Administration Committee. Strodel held the position until early 2014 when Ed Cassidy took over responsibilities. Cassidy retired from the position on December 31, 2015, and was replaced by Will Plaster. Plaster served as CAO until July 31, 2016. The current CAO, Phil Kiko, took office on August 1, 2016.

This is the relevant information: The current CAO, Phil Kiko, took office on August 1, 2016. Therefore, the final answer is Phil Kiko.
