I am at the point where I am starting to ask people for LORs. Do you think it makes a diff in peds what a person's title is? I have a physician in a specialty and the chief of that specialty both offering to write me letters. Would it hurt to submit letters from both in the same specialty?
Second question is if you know a physician well and think they will write you a good LOR do you think it matters if they are a DO vs an MD?
Thanks for your suggestions and thoughts!
Speaking as a fourth-year who recently matched:
When choosing letter writers, it's important to choose people who know you well, and can put more into their letter than, "Alice is a hard worker," or "James is extremely bright." You want the programs to which you're applying to be able to get a sense of the type of person you are, and how well you would fit with their department. Asking a "big name" to write you a letter simply because other people know who he or she is won't help you much, unless, of course, you've been fortunate enough to get to know that person well and work closely with them.
To answer your questions, I don't think it matters if you have multiple physicians from the same sub-specialty write letters for you, particularly if you're thinking about a fellowship in that area. Having said that, it's nice to have a "mix" of letters from physicians in different specialties, because each writer will be able to discuss your strengths as a medical student, and your interests outside of school, from a slightly different angle, which gives programs an even better idea of what you are like.
It also shouldn't matter if a physician trained at an allopathic or osteopathic school. To be perfectly honest with you, if a program didn't invite you for an interview simply because "a D.O. wrote one of your letters," that's probably not a program you want to be a part of.
Additionally, some programs may require a chairman's letter, or a letter from a pediatric clerkship director, so it would be worthwhile to meet with one of both of these people at your institution. Not only will they be able to write a letter for you, but they will also be able to give you an idea of where you should apply, based on board scores, grades, your interests, etc.
Good luck, and let me know if there's anything I can do for you.
