About Andrey Leonov, MD

Philosophy of Care

As an allergy, asthma and immunology specialist, I strive to provide my pediatric and adult patients in the Joliet and Lockport communities with the best care possible. Allergies and asthma can have a tremendous impact on your daily life. Whether you’re struggling with chronic sinus symptoms, food allergies or skin rashes, my goal is to work collaboratively with each patient to identify their specific allergens and develop a treatment plan best suited to their individual needs. In order to achieve the best outcomes, it’s essential that patients are included in the decision making process and feel well-informed and comfortable, both with me and their care plan.
