All-School Auction

Join Mater Dei High School for an unforgettable evening as we celebrate 75 years of HONOR, GLORY, and LOVE at the Diamond Anniversary & Ring of Honor Gala on Saturday, April 25, 2026. This elegant formal gala will feature fine dining, a Live Auction, and a special Ring of Honor program honoring individuals whose lasting contributions have shaped the Mater Dei legacy. 

We are excited to announce that our entertainment for the evening will feature the Matt Mauser Big Band!  The Matt Mauser Big Band - led by Mater Dei's own current parent Matt Mauser - channels the timeless charm of a young Frank Sinatra at the height of his career while also paying tribute to legendary artists like Elvis Presley, Tom Jones, and other acts from that iconic era.  

In addition to the live event, an exciting online auction will take place the week leading up to the Gala - April 20 through 27 - offering exclusive items and experiences. Proceeds from the Gala and auction support vital school-wide programs and innovative technology enhancements that benefit ALL Mater Dei students.  THE ONLINE AUCTION IS OPEN NOW!  CLICK HERE TO START BIDDING!

We look forward to welcoming you to this milestone event as we celebrate our past, honor our legacy, and invest in the future of Mater Dei. Contact Melinda Craft, Coordinator of Special Events, at [email protected] or (714) 850-9534 with any questions.
