Allergy and Asthma Care of St. Louis, with offices in both St. Louis and Chesterfield, has been dedicated to providing the most up-to-date treatment for adult and pediatric patients with allergy, asthma, or immunologic disorders since 1987. We offer world-class expertise and the highest standards in diagnostic testing and treatment for allergy, asthma and immunology.

In February 2015, Allergy and Asthma Care of St. Louis merged with Dr. Douglas Berson.  With his arrival, we have added additional office locations as well as expanded injection hours. We can now provide even more accessibility to accommodate your full treatment needs.

Our four physicians are board-certified by the American Board of Allergy and Immunology and together have over 80 years of practice experience to offer our patients. We hope you find this website informative. Our staff is looking forward to speaking with you in person!
