When Tony Podesta sends an invitation, smart people always say yes. But an invite from Tony and Walmart’s Senior Director of Federal Government Ivan Zapien to fete the outgoing Executive Vice President of Corporate Affairs Leslie Dach has all the smart people accepting.

Tosca’s front room was packed with Washington’s finest to take a moment away from big issues to celebrate a Big Man on the Washington Campus (Leslie, of course). After leading their Washington office for seven years, he’s leaving behind all the good works of the corporate affairs office to a new role as consultant to the company. Leslie with his wife Mary and their daughter hugged and chatted with friends as yummy hors d’oeuvres were passed around the early-evening crowd.

Guests included Sylvia Matthews, former director of OMB, who Leslie recruited to Walmart to run their philanthropy, Washington Super-Lawyer Bob Barnett, Martha’s Table CEO/President and Philanthropist Patty Stonesifer, Mary Tydings Smith and The New Yorker’s Jane Mayer. Other guests included Ron Brownstein and Eileen McMenamin, Amy Weiss and Peter Kadzik, Ann Walker Marchant, Melissa Moss and John Podesta.
