SANTA ANA, CA / BERWYN, PA (March 19, 2025) – Mater Dei High School, a prestigious institution with a national reputation for excellence in athletics, and Playfly Sports, the sports industry’s leading revenue maximizer, today announced the first-ever multimedia rights (MMR) agreement between an individual high school and a third-party partner. This 10-year partnership that spans through the 2034-35 school year will leverage Playfly's industry expertise to enhance sponsorship opportunities, media exposure, and fan engagement. Playfly will apply its proven approach that spans more than 27 collegiate athletic departments to deliver substantial revenue growth and breakthrough brand partnerships to Mater Dei. This collaboration will not only expand the Mater Dei brand regionally and nationally by amplifying the success of its teams and student-athletes but will also introduce new sponsorship opportunities that align with the school’s legacy of excellence. Additionally, Playfly will leverage its advanced digital strategies to enhance content creation, delivering more engaging storytelling across multiple platforms. Fans can also expect an elevated experience at the Santa Ana Bowl and on Mater Dei’s campus, with enhanced activations that deepen engagement. The partnership will further support the growth of Mater Dei’s online and gameday merchandising efforts, providing new ways for supporters to connect with the school’s storied athletic tradition. “Playfly’s explosive growth is driven by their unique expertise in monetization and fan engagement. We welcomed the opportunity to team up in further elevating the Mater Dei brand,” said Khaled Holmes ’08, Mater Dei Director of Development - Athletics. “Having had the chance to continue my athletic career at USC and in the NFL, I understand how innovative initiatives enhance the student-athlete experience. This alliance not only supports our student-athletes in new and exciting ways but also reinforces our commitment to leading the way in high school athletics.” The agreement is complemented by Playfly’s recent acquisition of Paragon Marketing Group and its deep expertise in high school sports marketing, event creation, live production, and social media. Paragon has a 20-year history of collaborating with Mater Dei athletics, representing multiple brands and orchestrating high-profile events that have showcased the school’s football and basketball teams on national broadcasts. Playfly will immediately team with Paragon to provide Mater Dei with expanded opportunities for media exposure, brand development, and innovative sponsorship activations. “At Playfly, we believe in the power of high school sports to connect communities and drive meaningful impact,” said Christy Hedgpeth, President of Playfly Sports Properties. “Mater Dei’s tradition of excellence, both academically and athletically, offers a full portfolio of compelling assets we can deliver to brands. This transformational collaboration is a testament to the growing opportunities in high school athletics.” “This relationship provides Mater Dei High School a greater ability to create, implement, and deliver a comprehensive and quality marketing, promotion, and media production program,” said Mater Dei President Michael Brennan. “By increasing this ability, we hope to provide more opportunities for those who seek a faith-based education. Our purpose will always be to utilize our resources to develop committed servant leaders that willfully choose goodness. We are grateful to be part of the Playfly family and excitedly welcome them to the Mater Dei family.” [video width="3840" height="2160" mp4="http://playfly.com/app/uploads/2025/03/Playfly-x-Mater-Dei_Partnership-Sizzle_FINAL.mp4"][/video] CONTACT: Allison Bergeron ‘96 Executive Director of Communications & Media Relations Mater Dei High School (E) abergeron@materdei.org Kyle Gurganious Director, Marketing and Communications Playfly Sports (E) kyle.gurganious@playfly.com
