The physician founders of Sentinel ER created it with a single goal in mind: to provide outstanding medical attention exceptionally fast. We offer a concierge approach to emergency care, treating every person who walks through our doors not just as a patient, but as a guest. This unique approach is reflected in every aspect of our Delaware emergency care center. From our comfortable, elegantly decorated lobby to our large private treatment rooms, we offer quick, thorough service. Our facility is unlike any other emergency room in Delaware. You will experience the highest level of care at no greater cost than a hospital emergency room.
