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.

Associate Professor of Clinical Pediatrics: Washington University Medical School

Attending Physician: Division of Allergy and Pulmonology, St. Louis Children's Hospital

Professional Affiliations

Working with our local American Lung Association teaches and reminds me that to be effective in the treatment of my patients with asthma and allergies, I need to "see" them in all their life setting, not just their office visits. Being aware of the difficulties in a home, workplace, or school is critical to developing and maintaining the right treatment plan for each asthmatic. Much of what doctors offer in terms of medications and therapies for asthma and allergies will only help if all the other variables in that patient's life are also taken into consideration. Helping to pull all of this together for my patients and seeing them achieve great results makes me excited to see each new patient.
