Dr. Ed Berman is Sacred Heart Hospital's audiologist.
When Dr. Cox had sent J.D. on an errand and J.D. zoned out, he asked Dr. Berman if he could re-create the lip movements so Dr. Berman could read the lips and tell him what was said. Either J.D. or Ed messed up, because the lips were not read properly and J.D. ran the wrong errand. ("My Long Goodbye")
