Philosophy of Care
I believe in careful listening and placing a priority on understanding each patient's picture of his or her illness. I think it is important to provide thorough information about treatment options and then trust my patients to make the best decisions for their health.
Allergy is a specialty where knowledge of the natural environment is necessary. I enjoy spending time outdoors and want to help my patients also to enjoy the many benefits of outdoor activity and recreation.
