Hello! I live out in the western suburbs. I have heard many good things about Homefirst. My close friend was planning to have her first child at home, but ended up having an emergency c-section several weeks early due to pre-eclampsia and ruptured placenta--obviously, she was screened out well and the problem was detected and she and baby were saved. She has gone on to have two wonderful home VBACs since then, with Homefirst. She definately feels that she would have had another c-section w/o the support of all the midwives, nurses and the doctor, and if she hadn't been at home.
Another friend was planning to use their services, but unfortunately she had a miscarriage at 15 weeks. She said that they were very supportive and understanding during her difficult time. She will use them when she gets pregnant again.
The family practice part has wonderful breastfeeding rates...something like 95%...and they leave the decision to vaccinate entirely up to the parent (no pressure either way). They only use antibiotics when there is a serious need. I'm pretty sure that they do not prescribe any artificial hormones (including hormonal b/c and HRT) or do permanent sterilization--this is mostly due to health concerns, rather than religious reasons (although there is some religious flavor there; Dr. Eisenstein is Jewish and many of the families who use them are strongly religious, of one type or another).
For my next birth, I am debating between Homefirst and a local midwife. I would love to do a home birth, but I'm not sure if Homefirst would be covered. Also, another concern is that many of the doctors seem to be men, and I enjoyed having a woman midwife for my last birth. For the midwife, it would be entirely covered, possible water birth...but under hospital control. I am not pregnant so there is still plenty of time to decide that one!
