If you have not yet submitted your application, you can go in and delete your previous recommender and then create a new submission. Please do not simply type over the name of the old recommender and put in a new name as the online form that is sent will not have the right information. Delete your first reference and create a new reference submission.
If you have already submitted your application, the system will not allow you to change your recommender. Please call our main Admissions office and we can send a new form to your new recommender.
