The host of a medical conference introduced two doctors, Gwen Burns and Seunghun Park, in the following way: "...Please welcome Dr. Seunghun Park and his colleague, Gwen Burns." What would be a more equitable way to make this introduction?
1) ...Please welcome Dr. Seunghun Park and Mrs. Gwen Burns.
2) ...Please welcome Dr. Seunghun Park and Dr. Gwen Burns.
3) ...Please welcome Dr. Park and Dr. Gwen.
