CalSouthern Faculty Mentors

CalSouthern’s faculty mentors are talented, highly credentialed educators who are also experienced practitioners in the subject areas in which they teach—and they use that practical experience to help learners apply the concepts they learn to current, real-world issues.

A common misconception about online learning is that it is impersonal, that learners are on their own. At CalSouthern, that could not be further from the truth. Faculty mentors get to know their students and provide one-on-one, personalized feedback on their assignments. They are also available by email, phone or Skype to answer their questions or provide any additional support or guidance they might need.
