Gerold Rosenberg is the officious receptionist at the MTI building on Grendel Avenue, whom April must get past in order to reach Jacob McAllen's office. If April is correct, the height and design of his desk give Gerold a smug sense of his own superiority. She deliberately baits him by repeatedly calling him "Jerry", which he evidently hates.
Gerold is voiced by Roger Raines.
The character model for Gerold is named "Gayman", which may indicate his sexual orientation. This is still no excuse for his outrageous fuchsia suit, however, even accounting for a 200-year gap in taste. The same model is used for the patron of the "Growing Pains" exhibition at the Roma Gallery. Jerry likes his art, too.
