DO's are pretty receptive to shadowing. Just find a few listed in your phone book with specialties that interest you, call their office, and ask them if they'd permit you to come in and shadow them for a while. That's what I did, and it worked really well (I spent 60 hours with a family doctor and 16 hours with a surgeon, 8 of which were in the OR.) Most younger DO's had to do the same thing when they were applying, so they know what it's like 🙂
