I went to their orientation on a couple weeks ago and got a really good feeling about both the current center "Healing Passages" and Kari who we spoke with. We don't have insurance so will be paying out of pocket. For a first pregnancy it'll cost us $5800. You may give them a call or go for another orientation (which is free).
The FAQ page on their site states:
Healing Passages Birth & Wellness Center represents the facility fee and we hope will be covered in-network. Willowsong Midwifery Care’s professional fee is covered as an out-of-network service by insurance plans. It is really important that you fully understand how your out-of-network coverage works. The birth center’s facility fee is separate from the professional fee of the midwives. The global fee for all prenatal care, birth, and postpartum services is significantly less than area hospital delivery charges, which makes your out-of-pocket costs comparable to, if not less than, a normal vaginal delivery at the hospital.
