Oral and Maxillofacial Surgery Assistant - OMSA The OMSA Committee and CALAOMS Board of Directors have been working to update the OMSA course. Our goal is to integrate the online self-study curriculum with the information given at the weekend seminars. It is our desire to provide a meaningful, relevant and well-supported educational experience for each assistant, regardless of his/her experience level. We do not have any more information to give you at this time; however we ask that you visit the CALAOMS website periodically and by the first part of August we will have the 2015 OMSA course schedule and updated information posted. Thank you.
