Kansas City Allergy & Asthma is the metro area’s premiere provider of allergy and asthma care. We have been serving the community since 1979 with three convenient locations in Overland Park, Olathe, and Lee’s Summit. We are proud to be expert caregivers and researchers for allergy, asthma, and immunologic diseases.

Our doctors are board-certified by the American Board of Allergy and Immunology which means we are proficient, knowledgeable specialists. We make extraordinary effort to stay up-to-date through continuing education in order to bring the best, most advanced technology to our patients.

We believe that no one should suffer from allergies. We are committed to providing the best possible care for each patient. We offer individualized, targeted care for long-lasting relief or even a cure. We use a team approach to work closely with your primary care physician to diagnose and treat allergies and asthma.

We are honored and privileged to care for you and your family.

We test and treat for virtually every allergic and immunologic condition. We employ cutting-edge diagnostics and offer treatment options for:

  • All types of allergies – food, hay fever/nasal conditions, insect stings, skin, drug
  • Pulmonary problems – asthma, sinusitis
  • Immunodeficiency

Allergies impact up to 80% of children and 70% of adults with asthma. Because of the close tie between allergies and asthma, allergy treatment is often the first step in an asthma care plan.

Our many testing procedures and treatments:


  • Allergy skin test for environmental allergens and food
  • Aspirin test and desensitization
  • Exercise challenge test
  • Local anesthetic test
  • Venom test


  • Allergy injections
  • Infusion therapy for immunodeficiency

For established patients, we offer extensive hours for allergy injections as well as same day ReadiClinic® for urgent needs that arise.

ReadiClinic®is a same day service. Visit guidelines are:

  • For established KCAA patients only.
  • We are not testing for COVID-19 at our office.
  • If you are concerned about symptoms/exposure to COVID-19, please call a KCAA nurse to discuss before visiting.
