Dr. Johnson is thorough and takes your healthcare seriously. He takes the time to answer your concerns and questions. The office staff is friendly and efficient.
in Belleville, IL |
Dr. William Johnson and Practitioner Katherine Shine provide expert consultation and compassionate care. Angie, Tiffany, and Janet are top notch support personnel and certainly make the office visits and allergy shots enjoyable. Our family is overwhelmed by the improvement in Emma's asthma/allergies since Dr. Johnson and Katherine Shine began managing her care. Our daughter is active and healthy with zero to minimal restrictions in her daily life. A+ Care!
Glen Carbon, IL |
My son's allergies are atypical and there isn't much known about his specific condition, but Dr. Johnson was familiar with it. He took his time reading our history and printed off research articles for us, highlighting parts that were pertinent to us. Even though there isn't much that can be done in our case other than waiting for him to outgrow it, he didn't want us to leave empty-handed, and I appreciated that. He was thorough, yet didn't put us through unnecessary tests.

After seeing a different allergist and getting no answers I made an appointment with Dr.Johnson. He was an excellent doctor! He took so much time listening and explaining things to me that many, many doctors, including my last allergist, have not taken the time to explain. I did not feel rushed at all and I honestly felt like he was truly trying trying to help me. I will recommend him to everyone I know.

After 25 years of seeing different allergists for myself and my children, I find Dr. William Johnson is very professional, thorough and helped my severe reactions to allergens effectively. I moved out of state for two years but will be returning to Scott AFB and Dr. Johnson's care. I highly recommend him!
