About us

Built on clinical experience, focused on research

Allergy Centre Research operates in partnership with Dandelion Allergy Centre, a multi-site allergy and immunology practice with clinics in Mississauga, Milton, and Toronto.

Operating in Ontario since 2015, our clinics provide allergy and immunology care to pediatric and adult patients, with a high referral volume from family physicians, pediatricians, and specialists across the region. That gives our studies access to a large, diverse patient population.

We collaborate with pharmaceutical sponsors, contract research organizations, and academic partners across asthma, food allergy, chronic urticaria, atopic dermatitis, allergic rhinitis, and immunologic disorders.
