C.G.
There is a big practice of midwives in this area, Midwest Midwifery (www.midwestmidwifery.com). I checked their website and they do have an office in Elgin. I have heard great things about them for birth although I have only been to them for well-woman care.
Homefirst (www.homefirst.com) is a holistically/naturally minded group of family practice MDs who do homebirth as well as hospital birth. I think they may have a midwife or two on staff, but I think most of the deliveries are done by docs. We see them for family practice and they are great.
Both of the above are covered in Blue Cross Blue Shield networks, but I am not sure about others.
Good luck with your pregnancy- I highly recommend a midwife over an MD. I am an L & D RN and midwives tend to be lower-intervention and more hands-on. Illinois has one of the highest rates of c-sections and also one of the highest rates of complications in the US, so every little chance of reducing problems is well worth it.
