dd is in college in DC and has been having stomach issues... I would rather she start with seeing someone local in DC vs coming home for an appointment. Do you guys have any recommendations for an excellent Gastroenterologist who is kind, has a good bedside manner, as well as an excellent clinician? Bonus points if the office is in DC proper. TIA!
