If you're considering a birth center, you won't need to find Dr. Right, as the person and the place are a package. Read over the questions for hospitals, too, as some will apply to these centers as well. Most questions do not though, because birth centers typically have low intervention rates and little opportunity or interest in separating you from your baby, partner, or friends.
Most birth centers have CNMs on the staff even if there are doctors as well.
If you're considering a center that doesn't have any CNMs, be sure and ask about their hospital-transfer rate and use of drugs. Transfer rates vary among birth centers, and if your birth center has a higher rate than average, ask why. They usually are, and the overall cost generally is far cheaper than hospital rates. Midwives often spend up to an hour with you during each monthly visit. Cesareans, of course, are not performed at birth centers, but women who need them are transferred to a hospital.
