Coming Soon: Freemont, California
Food Allergy Institute is excited to announce the launch of its first affiliate site, opening this summer in Fremont, California! Through our growing affiliate program, we partner with providers across the U.S. to expand access to Food Freedom through the Tolerance Induction Program™ (TIP). While all new patients will continue to begin treatment at our Southern California locations, the Fremont site will support active patients by performing food challenges closer to home.

"Food Allergy Institute's comprehensive evidence-based approach takes the guesswork and fear out of food allergen immunotherapy for families who believe in a science-based approach to healing food allergies and are ready to get started. I feel confident referring to their program and co-managing my patients with the FAI team.

Michael VillaDelgado
MD, Fellow of the American Academy of Pediatrics (FAAP)
With over 25 years of experience, Dr. Michael Villadelgado brings trusted, compassionate pediatric care to Orange County Children’s Medical Group, specializing in mental health, neurodevelopmental, sleep, gastrointestinal, and immune-related conditions.
“As a healthcare provider, I've always strived to offer the best possible care and options to my patients, especially those with food allergies. Referring them to the Tolerance Induction Program for many years has been educational, life-changing, and revolutionary. Witnessing the remarkable results that my patients have achieved under their expert care has been nothing short of inspiring. Their unique process of introducing biosimilar proteins initially and the unique delivery system in place has been highly effective with lower adverse events and higher compliance among my patients. From reducing and eliminating the severity of allergic reactions to expanding dietary options, the outcomes have been transformative in the lives of many children.
Collaborating with Dr. Randhawa and his dedicated team reinforces my confidence in providing comprehensive care and ensuring my patients receive the highest standard of treatment
available.”
