The program is very DO friendly. Our current intern class has 4 DO's.
It can be inconvenient not speaking fluent spanish since ~70% are spanish only, but as I've been here, I've picked up the phrases I need to say and I can do most things on my own. Some of the interns had spanish in college or HS which made it easier to pick up again. That being said, I believe about 20% of the 70 do speak some english, they're just afraid they don't speak it well enough, just as I might say I only speak english if I were to go to a hospital in Mexico. Every patient I've interacted with has been very helpful and some even help me with phrases I've butchered. Most of them know numbers in english, which I have a problem with for some reason. I took latin in HS and so was at a real disadvantage. Its only when I need to explain a procedure in detail, or need to answer a complex question does it become necessary to get a translator. In the ED, the nurses are frequently in the room and its pretty easy to get them to translate. I've never had to wait more than 5 min to get someone to help me, and that was on an off service rotation.
