how long do you have to be in school to be a pediatrician ?

Hey Katherina -- I answered this over on this other question on CareerVillage: How many years does it take to become a pediatrician? What does this career path look like specifically?. Check it out and comment over there if you have any questions.

Basically, the answer to your question is "8-13 years depending on how you want to count (whether you include your 3-5 years of residency as 'education' or not".
