Our mission is to provide patient-centered care for allergies and asthma.

About Us

From convenient locations across the West Coast to patient-centered clinical solutions, our most important commitment is the lasting well-being of every individual who walks through our doors.

Our mission is to provide personalized care for allergies and asthma.

From our earliest days, we have been a pioneer in breakthrough customized approaches to treating asthma and allergy, including desentization treatments for shrimp and nut allergies. Through it all, we have always ensured that our treatments fit our patients’ real lives.

Our Philosophy

We treat asthma and allergies through a patient-focused approach that views every person as an individual with unique challenges and goals. We set ourselves apart from other allergy clinics in multiple areas, including:

Experience

The practice’s Sanjeev Jain, MD, PhD, was the first doctor in the world to successfully desensitize patients from shrimp allergies, and his achievements don’t stand alone.

Diversity

We have a culturally diverse staff of highly trained physicians, nurses, and medical assistants, including experts in allergies, immunology, pediatrics, and internal medicine.

Personalization

Patients at Columbia Allergy enjoy comprehensive care—where no issue is too specialized—in order to get the most out of each appointment.
