Who will deliver the baby here?

Priya

Am visiting a obgyn office for regular visits and they deliver the babies in a linked hospital. The obgyn office encouraged me to meet different doctors each visit so am familiar with all doctors in facility before I deliver. I doubt if those doctors will actually be available at my labor. I mean on duty doctors or midwives deliver the baby or they actually inform the doctors linked to the clinic? Am confused. First time having a baby here. Pls help.
