Here's the situation. For my recommendation letters, most schools require one from either DO or MD or an employer, which in my case, the ER coordinator at the hosptial I work at. I have shadowed a DO for a couple of weeks. He was very friendly and more than happy to write a letter and I have reason to believe that his letter would be good, not necessarily a strong one though. I also have a MD from where I work who offered to write a recommendation letter for me. I have worked side-by-side with him several times, but because the ER setting, I don't get to spend a lot of time with him. Once again, I believe he will write me a good one, possibly a strong one though I'm not sure. And then there's the ER coordinator/charge nurse who supervises everyone on the same shift I work on. And since she's supervising, she's seen me capable of doing a lot and having the qualities to be an excellent physician. She has also known me for a year and I feel she will be able to write me a strong letter....however, her title is RN which I'm not sure will be as favored upon over a letter from a MD or DO in the eyes of the admissions committee. So what do you think I should do?
