First, a disclaimer. I am looking for a twin vbac provider, so it's a lot more limited than just twins. However, the list below is the recommendations I have received around these boards and elsewhere.
Dr. Julie Ericson (www.womenobgyn.net
Dr. Elias Sabbagha (I know he is know for doing breech births, common w/twins)
Dr. James Smith (www.obgyneassociates.com
) (this is the one I am choosing, for location, insurance coverage, he returned my call and didn't seem bothered by the fact it is a vbac. He has 3 midwives under him. However, he is not the most comfortable with a 2nd twin breech so we'll see how it goes.)
I also tried to get in touch with Dr. Kovio (sp?) who is with the midwives that left Midwest Midwifery. You'll see some thread about them here. They might be an option as well.
There are also traveling homebirth midwives that do twins, if that is within your comfort zone. You can see a response to my question on the ICANofChicago Yahoo group.
