2 experiences. I birthed at Providence in 2004 and I didn't care for it at all (at that time, the postpartum unit had shared bathrooms between multiple postpartum women, ICK). My daughter was in the NICU and got good care there for the most part.
I went to Anchorage Women's Clinic yesterday for a 2 week post-op on a c-section (i didn't have it with them, we just moved to Anchorage - had the c-section in Bethel) and the doctor I saw was lovely. They seem very "natural friendly" but I could be way off on that. They offer hypnobirthing classes, the doctor mentioned whether or not I'd be nursing "1 or 2 years" with a big smile... I think that'd bode well for the general mindset of their practice.
I've "heard" that Prov L&D is understaffed and that you may benefit from a doula if you deliver there. I'd imagine that if a midwife has a clinic practice she probably isn't going to be hanging out in L&D unless it's at night and/or they're on call... the delivery I had there I was only in the hospital for about 20 minutes before the baby arrived so I don't know what it's like to labor there.
Not sure if any of this helps you
