I'm applying for MedPeds next year and I'm in the process of trying to get some of my letters together. In looking at the LOR requirements for all of the programs I see that many of the programs require a letter from the Department "Chairs". I have not had much contact with the Departments chairs of either the Medicine or Peds nor have I been in a clinical environment with them either. How should I approach them to write me a letter if I don't know them very well? Any feedback welcomed!!
