You can disconnect from an organization if you would like it removed from your list of "My Organizations". Do this by signing into your account at app.securegive.com

When signing in using the link provided, you should land on the "My Organizations" screen. If you do not, you can choose it from your account menu. 

To the upper right of that screen, you will see a button titled "Manage Organizations".

Click here and you will see the option to Remove listed under each organization's information. Simply click "Remove" and it will drop off of your page. When you are done, you can click the "Done" button to the upper right. If you have a recurring transaction setup to an organization, you will see a message stating that you cannot remove the organization.
