FOR IMMEDIATE RELEASE

Allergy & Asthma Associates of Southern California Joins Modena Health; Dr. Warner Carr Named Chief Strategy Officer

Nationally recognized allergy and immunology leader brings clinical expertise, research experience, and strategic vision to Modena’s next chapter

LAGUNA NIGUEL, Calif., Nov. 10, 2026 — Modena Health today announced the acquisition of Allergy & Asthma Associates of Southern California in Laguna Niguel and the appointment of Warner Carr, MD, as Chief Strategy Officer. An accomplished clinician, researcher and educator, Dr. Carr brings extensive expertise in oral immunotherapy, clinical research, and physician advocacy to his new role, where he will work alongside Modena’s leadership to guide the organization’s national growth and advance specialty care.

The acquisition builds on Dr. Carr’s longstanding presence in Orange County, where his practice has served thousands of children, adults, and families from Laguna Niguel and surrounding communities. It brings together a locally established practice and a growing organization with a shared commitment to personalized allergy and asthma care.

“Dr. Carr has built meaningful relationships with patients and families throughout Orange County while contributing to the advancement of our specialty,” said Brian Modena, MD, Founder and CEO of Modena Health. “His clinical knowledge, leadership experience, and understanding of community-based medicine will be invaluable as we expand access to care. We are excited to welcome him as both a colleague and a strategic leader.”

Dr. Carr brings extensive expertise in food allergy and oral immunotherapy, known as OIT. As founder of the Food Allergy Center at Allergy & Asthma Associates of Southern California, he has helped families navigate food allergy treatment and contributed to research advancing the field. His publications include co-authorship of the landmark peanut oral immunotherapy study published in The New England Journal of Medicine, as well as research examining multi-food oral immunotherapy. As a principal investigator in numerous clinical trials and a former medical officer at the U.S. Food and Drug Administration, Dr. Carr has seen treatment development from both sides: conducting studies with patients and evaluating them as a regulator. That experience will support Orso Health, Modena’s clinical research network, as it expands access to clinical trials for patients across Modena’s communities.

His leadership extends beyond his own practice. Dr. Carr has served on the American College of Allergy, Asthma & Immunology’s Board of Regents and as chair of its Advocacy Council, helping address issues affecting allergy specialists and the patients they serve.

In his role as Chief Strategy Officer, Dr. Carr will help guide Modena’s strategic direction, with an emphasis on expanding access to specialty care, advancing food allergy programs, growing clinical research through Orso Health, and strengthening collaboration among physicians across the organization. His perspective will help inform how Modena grows while preserving the personal relationships at the center of community medicine.

“Caring for families in Orange County has been one of the most meaningful parts of my career,” said Dr. Carr. “Joining Modena creates an opportunity to build on that work and contribute to a broader vision for allergy and asthma care. I look forward to working with Dr. Modena and the team to support our physicians, advance food allergy treatment, and reach more patients who need our expertise.”

For Modena, the acquisition represents an investment in both the Orange County community and the clinical leadership that will shape its future. The organization’s approach centers on combining specialty expertise with attentive, individualized care for patients and families.

The Laguna Niguel office is located at 28202 Cabot Road, Suite 105, Laguna Niguel, CA 92677 and is currently accepting new patients. To learn more about Modena Allergy + Asthma – Laguna Niguel, please visit www.modena-health.com/laguna-niguel.
