We went to fun Halloween parties on Friday night, starting at the Carnegie Library in Mount Vernon Square.

The annual Carnegie Halloween Party has become a top event, bringing in hundreds of costumed DC young professionals. We snapped DOJ’s Brian Holder with Home Health Care’s Lisa Garrett.

Enjoying the band on the main level: Three Blind Mice, Sneha Chili, Tina Ahn, and Laura Kost, surround Danielle Fox.

The party spread out over many levels, each with open bars, music, and dancing to DJs and bands. Here, J. Alexander Pilon and Dawn Griffin.

The VIP area on the top level of the library had several open bars and its own dance floor and DJ. Here, University Club’s Tanveer Kathawalla and Bill Callahan with Georgetown Medicine’s Luke Sheen.

Remedy Health Media’s Brittany Lee, ACHP’s Karlee Averett, Balance Gym’s Erin Sleigh, and Rasmus Auctions’ Marie Jarvis.
