"I'm thrilled to be joining the AHIP team, and couldn't be more excited for the challenge," Buck said in a statement. "This is an industry going through an unprecedented transition, and health plans need as strong a voice as ever as they seek to provide Americans affordable, quality private coverage."
Buck's new job will be quite a change from his current job. AHIP is deeply invested in the implementation and success of the Affordable Care Act. For the last three years Buck has served as a key voice for the GOP's efforts to repeal the law.
AHIP President Karen Ignani on Monday announced Buck as the group's new spokesman and vice president of communications.
"Brendan's experience and skill set will allow him to hit the ground running on day one," she said. "He's an effective communicator who knows how to tackle complex policy issues and skillfully navigate an ever-changing health care and media environment. We are delighted to welcome him to our team."
Buck is a veteran of Republican politics, having previously working for numerous House GOP lawmakers.
