Affiliate Sites

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.

I feel confident referring to their program and co-managing my patients with the FAI team.

Founder and Medical Director of Ocean Pediatrics, Dr. Abelowitz is a leader in the field of pediatric medicine, with a vast expertise in academic and clinical settings. He has been treating children in the Orange County area for over 29 years.

“The primary challenges my patients encounter with food allergies are lifestyle limitations, anxiety, and fear related to the dangers of food allergy, especially anaphylaxis, multiple doctor and ER visits, consistent need for medication refills, especially Epipens and Avi-Q, as well as the constant, tedious need to constantly
Complete medical forms such as school allergy and medication administration forms.

reach remission is an overwhelming sense of relief by the patient but especially the parents, increased confidence, and reduced anxiety.”

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.”

"What a wonderful option for treating our patients with severe food allergies! Having options outside of avoidance is really a game
changer for food allergy patients. The Food Allergy Institute is a family-friendly center of excellence that offers patients the potential to significantly reduce the risk of anaphylaxis long term, and to live fuller, more normal lives without constant worry."

Youhanna S. Al-Tawil

MD, Pediatric Gastroenterology
GI For Kids is a Knoxville, TN based pediatric gastroenterology and nutrition practice committed to providing excellent care that is both affordable and accessible. As a medical director and founder of GI For Kids, I have recognized that food allergies can play a significant role in the health and well-being of our pediatric gastroenterology patients.  
 
We believe that food allergies in children don’t just impact daily life but can also be life-threatening. We have unfortunately been limited in the past for treatments other than strict avoidance. The Food Allergy Institute has now changed this, and as a result, many patients have had their lives transformed through their program. The Food Allergy Institute in southern California has been a life-saving institution for many patients and families.  We are so excited that this program can now be more accessible to the patients and families on the east coast as well.
