Betty Dombrow was a patient at Sacred Heart Hospital.
Betty was under the care of Elliot Reid, and had given up hope on life. When Elliot asked if there was anything she could do to make her hold on to life, Betty asked to see her dog. Elliot snuck Boomer into the hospital with the help of Janitor, and Betty was extremely happy. Dr. Robert Kelso found out about the dog and suspended Elliot. Elliot argued that the dog gave Betty the will to live, but Dr. Kelso revealed that Betty had passed away hours earlier. ("My No Good Reason")
- Boomer, her pet dog.
