“I think each patient should be cared for in a caring, friendly way that is compassionate. I try to be relaxed with patients, but also weigh risks and benefits in a serious manner. Conditions like asthma and food allergies can be serious. I try to find good strategies for coping in addition to state of the art diagnostics and medication to get the best outcomes for every patient.”
