Physician re-entry programs are a great idea, but that one sounds really expensive! I know of a really good one for anesthesiologists, and it is only $1000/month. I wonder if that one you found is more for people who have lost their medical licenses and have to be "re-educated." When I was searching at one point, I found a program like that that was about $14,000, but it didn't even involve any patient care!
Talking with other pediatricians directly sounds like a great idea. Good luck!
