The residential college deans are members of the Yale College Dean's Office located in each of the twelve residential colleges. The college deans are in general charge of their students' academic welfare and progress. They know their students well, and whenever an instructor wishes to discuss any matter relating to a student's situation, the residential college dean is almost always the first and best person to call. Residential college deans are eager to cooperate in any way possible with instructors, and instructors are urged to take full advantage of the assistance that a college dean may be able to supply. The Yale College Dean's Office Directory provides contact information for the residential college deans.
