"Hello, my name is releehw and I'm a sophomore in college who wants to go to medical school. I'm looking to try to get some clinical exposure and I am interested in observing the day to day routine of pediatric dermatological neurosurgery. Would you be willing to let me shadow you for [length of time]? If not, would you be able to point me towards someone who might be able to assist me with setting up shadowing? Thank you, I really appreciate it"
