I am currently a DB fellow in one of the top ten pediatric hospital.
when I applied for the fellowship, i have lots of interviews. Of the 20 programs that I applied, I have 10 interviews and I have seen the differences between programs. There are programs that focus a lot in behavior while others focus in developmental disabilities. The programs I am training in now has its major focus in developmental disabilities, however, we are evolving and we have recurit several DB pediatricians that will focus on the behavioral issues.
DB physician will be in high devmands because there are not enough to go by in the entire country especially to the minorities population, which has high demands. In addition, your life style will be very different to your hardcore medicine colleagues. You will have time for your family and not to worry about being waken up in the middle of the night. I hope that will help.
