    About Conrad Prebys Foundation

    The Conrad Prebys Foundation concentrates its philanthropic resources on high-impact scientific research in San Diego, exemplified by a single multi‑million dollar gift to the Salk Institute.

    About Conrad Prebys Foundation

    A $6.7 million grant to the Salk Institute for Biological Studies for the "Salk Campaign for the Future: Building a More Resilient World" captures The Conrad Prebys Foundation’s pattern: large, institution-level support for San Diego science. The foundation’s recent giving also reaches a similar scale at Sanford Burnham Prebys Med Disc Inst, where it backed both "Catalyst the Teaching Incubator" and research tied to breakthrough therapies for medulloblastoma and other cancers. That mix shows a funder focused on biomedical research infrastructure, translational science, and the institutions that carry it out. Other major grants point to a broad local portfolio built around health and science. The foundation has supported Rady Children’s Hospital for rapid precision medicine, La Jolla Institute for Immunology for a named flow cytometry core, and The Scripps Research Institute for immuno-oncology and cell therapy platforms. Its recent awards also include operating support for major San Diego institutions, suggesting that it uses both project-specific capital and flexible general support to sustain research capacity and related civic organizations. The result is a grantmaker centered on San Diego institutions, with a clear preference for high-dollar commitments that strengthen research environments, medical innovation, and community-serving organizations tied to health and science.

    What Conrad Prebys Foundation Funds

    Biomedical research is the clearest throughline in the foundation’s grantmaking. It gave $1.2 million to Rady Children’s Hospital for "Rapid Precision Medicine at Rady Childrens," and $975,181 to The Scripps Research Institute for "Trispecific Antibodies: Next Generation Immuno-Oncology Platform for Treating Relapsed / Refractory Cancers." Another grant, $700,000 to The Scripps Research Institute, supported "Development of Allogeneic Switchable Chimeric Antigen Receptor T Cell Therapy." The foundation also funds research infrastructure. It awarded $1,169,810 to La Jolla Institute for Immunology for "The Conrad Prebys Foundation Flow Cytometry Core at La Jolla Institute for Immunology," and $1 million to Sanford Burnham Prebys Med Disc Inst for "Gemfinder - Serving the Underserved." Its grantmaking extends beyond lab science into arts and community well-being. San Diego Symphony Orchestra Association received $3 million for general operating support, and Ntc Foundation received $500,000 for "Building 178 Performing Arts Center (Working Title)."
