Agree with Brenden, but I'd recommend to join on DocumentModifiedByUserID instead of Owner - this will give you the last user, who updates the document, meanwhile Owner might be some admin or developer (creator):
SELECT DocumentName, NodeAliasPath, DocumentCreatedWhen, DocumentModifiedWhen, UserName, FullName, Email
FROM View_CMS_Tree_Joined
LEFT OUTER JOIN CMS_User ON DocumentModifiedByUserID = UserID
