Toward the end of season five, the bubbly and naive Erin Hannon (Ellie Kemper) is introduced as Pam's replacement at reception following Pam's short stint at the Michael Scott Paper Company and subsequent move to sales. A story arc at the end of season four has Holly Flax (Amy Ryan) transferred to the office as Toby's replacement. She becomes a love interest for Michael, as they share very similar personality traits. Jo Bennett (Kathy Bates) is the CEO of Sabre. This company takes over Dunder Mifflin, and Gabe Lewis (Zach Woods), introduced in the middle of season six, is a Sabre employee who is assigned to the Dunder Mifflin Scranton branch as the regional director of sales. In season seven, Bennett's friend Nellie Bertram (Catherine Tate) is interviewed to replace Scott and later serves as a replacement regional manager for Bernard in season eight after Robert California (James Spader) has become the new CEO of Sabre. In season nine, Clark Green (Clark Duke) and Pete Miller (Jake Lacy) join as new customer service representatives who attempt to catch up on the ignored customer service complaints that Kelly has neglected while working at Dunder Mifflin. Clark is later moved to sales.
