A seventh-grade social studies teacher at Mount Vernon Presbyterian School in Sandy Springs was one of 20 teachers from across the country who visited the White House on Wednesday for a Teacher Appreciation Week event.

The teacher, Alex Bragg, was participating in a conversation with administration officials including Education Secretary Arne Duncan and Jill Biden, a lifelong educator and wife of Vice President Joe Biden.

The group of teachers also was taking a tour of the White House and sharing a cup of tea with Biden.
