We see Dr.Minkus who works through what was known as Evanston Hospital (it has another name now and I'm drawing a blank). He has been a wonderful doc - we do not vaccinate, refuse most "routine" testing and do not keep the visit schedule as dictated by AAP. Dr. Minkus supports our decisions and always has warm, kind and supporting words for us regarding all of the "alternative" things we do. He promotes extended breastfeeding and homebirth (in fact he was just in Springfield speaking to congress regarding the legal rights of homebirth midwives in Illinois). He has never recommended any conventional medicines for our son and supports our decision to use homeopathics. He believes that an educated, loving, and open-hearted parent is competent to make most, if not all, medical decisions regarding their child.
My father-in-law is an MD ("retired" orthopedic surgeon)who is in the process of opening a homeopathic/integrative medicine clinic in St. Charles - its pretty far south-west and he does not treat children, but if you ever needed a consultation or advice about homeopathy he would be more than happy to help. He may be able to help you find a practitioner in your area as he is pretty networked.
And, just as an aside, HomeFirst is a huge group here that practices "alternative" medicine, but those who I know who have gone to them have had a number of issues with their practice. Some have complained of some crazy billing problems and having a hard time getting in to see the doc of their choice. Also, it is a heavily Christian based group and more than once I have heard of the doctors praying during a homebirth labor/delivery. That's cool if it's your thing - I am sure that prayer is a very powerful and comforting thing to some women during that time - but the women I know who birthed with them are Jewish like me and really did not want that type of prayer. Just seemed kind of strange to them that nobody asked the what their wishes were in regards to that.
Good luck with your move and welcome to the area!
