Mater Dei in Santa Ana was founded in 1950 as the first co-educational Catholic high school in Orange County. The school opened with 111 students who chose “Monarchs” as the team name and the lion as its mascot. In 1953 the first graduating class stepped forward and began the legacy of more than 27,000 Monarchs who have played an integral role in the fabric of Orange County’s community and the nation.
