Founded by educational leader Stanley Bosworth, the Saint Ann's School is a private campus well known for it's artistic and academic achievements.  The flagship location is at Pierrepont and Clinton in Brooklyn Heights.  Since 1966, the school has occupied the 12-story Bosworth Building and constantly changed over the years as the successful institution grew.

In 2015, Yorke Construction was retained as the construction manager and charged with (once and for all) updating the building to maximize efficiency and better suit the school's needs.  The project consists of general aesthetic updates, overhaul of the building's electrical, fire alarm, mechanical, fire sprinkler and plumbing services, providing a new top-of-the-line commercial kitchen for the cafeteria, intelligent classrooms, and new grand staircases and state-of-the-art performance spaces.
