Professional Notes

Dr. Johnson joined Esse Health after completing a fellowship in Immunology at Washington University School of Medicine.

Solid Educational Foundation

Taking care of the hospitalized asthmatic patient during my residency and fellowship training was always one of my favorite tasks. Each patient was so different in spite of having basically the same underlying disease. Following those patients in my clinic afterwards taught me the importance of accurately identifying their individual asthma triggers so that future episodes could be prevented. Giving them the information they needed to keep their asthma and allergies in good control was exciting, and seeing them succeed to lead normal lives was rewarding. Today, with improved medicines and monitoring techniques, we know that most asthmatics can lead normal lives and participate in a variety of activities.

A Respected Professor and Teacher

Serving the patients of Children’s Hospital over the years has been a great way to repay the educational opportunities they offered me during my fellowship in Allergy and Immunology there. Helping to teach and interact within their residency and specialty care programs, I benefit by staying up to date on the latest information and research in the field. I find the educational benefits of working with my colleagues at the Washington University Medical Center invaluable when taking care of my own pediatric and adult patients.
