What: Preservation Houston's Pier & Beam #throwbackthursday party.

Where: The lobby of the historic Esperson Building in downtown Houston.

The 411: The one year anniversary of this dedicated young professional group was reason enough for a lively celebration among the city's next generation of leadership with an affinity for Houston's growing preservation movement. Party chairs Mary Hammon Lee, Dave Morris, Nick Senkel and Claire Cormier-Thielke welcomed the young preservationists some 200 strong.

Several guests grooved on the #throwbackthursday theme by stepping out in retro threads while others carried books on historic Houston. And, yes, the conversation centered frequently on historic buildings in their various neighborhoods. Good eats from Elegant Events and Catering by Michael combined with libations from five vendors kept the partygoers fueled.

The event was a home run for Cameron Management which on this night showcased the beautifully restored building. Thank you Cameron Management president and owner Dougal Cameron and Cameron marketing director Jano Nixon Kelley.

Who: Preservation Houston's executive director Stephanie Ann Jones, VP of strategic planning Elizabeth Husseini and Pier & Beam members including Laura Menges, Austin Thomas, Mike Mahlstedt, Will McCallum, Abby Noebels, Julie and Ian Rosenberg, Neal Sarkar, Rebecca Schmidt and Claudia Solis.
