You might be wondering why you should go to an allergist instead of your primary physician. Primary physicians treat all types of ailments, but generally do not have the specialized training in any specific area of medicine. An allergist specializes in the diagnosis and treatment of:

  • Allergies
  • Asthma
  • Diseases of the immune system

If you believe you are suffering from allergies and wondering, “Should I see An Allergist”, Dakota Allergy & Asthma has developed this Allergy Assessment to help.  If you determine you need to see an Allergist, the Dakota Allergy & Asthma team is ready to answer your questions and get you on the course to feeling better.
