US-MD PGY-1 here, it gets tricky. A lot of DO-specific programs will naturally overlook you as an MD, let alone a Top20 US-MD candidate. Unless you have a.) away-rotated there or b.) have an INSANE connection there, I would not risk wasting a signal on a DO-heavy program in 2025. Alot of these DO-heavy programs will "protect" spots for DOs to preserve their presence in the field (and rightfully so given the competetive nature of the application process). Programs that come to mind are Orange Park and Hackensack - these programs take a massive majority DO with the occasional MD every other/few years. I'm willing to bet that MD had an incredibly impressive away-rotation there or a close mentor who knew the PD vouched heavily for the student.

< have spoken with the most recently matched MD at Orange Park and they confirmed they indeed do an away rotation. If there is a DO-friendly program you are serioualy interested in, you should do an away there to show you're seerious.
