Information about Allergy, Asthma & Immunology


Gain control over your allergies

Our three-person physician team is certified by the American Board of Allergy and Immunology and provides high-quality care for children and adults. As allergists, we listen closely to understand your health issues and goals. From there, we perform comprehensive evaluations and allergy testing, and work with you to develop a plan to manage and treat symptoms. Our recommendations are based on the latest clinical research and evidence—approaches that are proven to help.

We offer allergist appointments at three clinic locations: Salmon Creek, 87th Avenue, and Columbia Tech Center. Our extended hours—8 a.m. to 6 p.m. on weekdays—make it easier to get the care you need, from follow-up appointments to regular allergy shots from our nurses.

Pollen Counts

Get today’s pollen count

Get an accurate picture of what might be causing your sniffling and sneezing and take steps to prevent those symptoms. Our Salmon Creek office is an official pollen counting station. Three days a week, during peak allergy season, Dr. Raj Srinivasan, Allergy and Pulmonology department chair, collects data from the Rotorod machine on the clinic’s roof. He counts the number and type of pollen grains to find out just how many allergens are suspended in Vancouver’s air.
