From corporate training sessions and seminars to large-scale conferences, NYSEC has a space for you.  The Concert Hall, known primarily for its grandeur and superb acoustics, can accommodate 800 and comes with a 16 x 16 screen, which makes any presentation smart and accessible.  Adler Study and Elliott Library often serve as “breakout” rooms for smaller meetings or lunches.  For mid-size meetings, Ceremonial Hall may be the right choice.
