Mark Datuin,
AuD
Audiologist
Dr. Mark Datuin joined Mission Audiology in 2018. As a native of Orange County, he is thrilled to be able to serve the same community where he grew up and continues to live. Mark was inspired to pursue a career as an audiologist through his deep appreciation for live music and the performing arts. He cherishes the ability to hear well, which drives him to help patients improve their hearing to not only connect better with their friends and family, but also to maximize their enjoyment of live performances, music, movies, and television.
Dr. Datuin obtained his undergraduate degree in psychology at UC Irvine and his Doctorate of Audiology from a joint program of UC San Diego and San Diego State University.
