The Mensa Headquarters is the New York headquarters for Mensa, an organization open to people who score at the 98th percentile or higher on official intelligence tests.


In 1997, the Extreme Ghostbusters investigated Mesa headquarters in search of the Sphinx but missed him. Everyone inside was already drained of their brain waves by the creature and they still had no clue where else he would strike.
