Would love input, in particular aProgDirector and anyone else with an insider's perspective: I am seriously considering doing a second residency in internal medicine after completing my dermatology residency. I just talked to a resident at a top-2 Northeastern program in Boston who switched in to internal medicine as a PGY2 after completing intern year and a year of radiology. He said it is extremely difficult to match into a top program. His board scores were stellar, for both Steps, as I gathered. But I think many people may be interested in getting double boarded, and wonder about the process, particularly if there would be a funding obstacle.
