First start with your parents’ doctors or the doctors of close friends/family friends. They’ll be more likely to help you out.
Then consider volunteer programs at hospitals nearby your home. You might have to start with something outside the clinical space like working in the gift store. The point is to get your foot in the door at the hospital to start building relationships.
Lastly, talk to your community leaders (teachers, priests/imams/rabbis/gurus/pandits, councilmen, etc) to see if they can connect you with a doctor on a personal level.
