Dental Assisting

A Centers of Excellence study estimated more than 3,500 dental assisting jobs would become available between 2017 and 2022 in the Inland Empire and desert regions. That’s an increase of 14 percent. So if you’re considering this field, you’ll be in high demand. 

Traditionally the program is two semesters.  COVID has delayed our schedule. The cost of the program is approximately $800 per semester.
