I've had 2 homebirths with Nancy and had fabulous experiences both times.
My dh was not super on-board with HB to begin with, but with lots of reading and talking and meeting Nancy, he came around and is now a huge HB advocate!
I've also attended a couple of friends' births with her and know many, many women who've birthed with her and had great experiences. There are many reasons why I like and respect her, but there's also just the 'click' factor. I felt like I clicked well with her- more so than the other 2 midwives I met and interviewed. I like and respect both of the other ones very much, and would have felt comfortable with them attending my births, but I just felt more 'right' with Nancy.
My dh also liked Nancy b/c she's smart and could read and interpret the scientific literature easily w/him (he's a scientist) and he felt like she really "knew her stuff." Again, not that the other ones don't, just that he also had more of a comfortable feeling with her.
For ME, her CNM status was a non-issue in my choice of MW, but for DH, it somehow helped him feel like she was more "official" and he felt a bit more at ease b/c of it. We could also file insurance w/her b/c of her legal status, and that helped convince him a bit too. (though we ended up paying 100%out of pocket for both births and it was TOTALLY worth it)
The other "midwife in Garner" is also very experienced, and has a well-deserved great reputation. I know many women who have birthed with her and have been very happy as well. She's kind and caring and knowledgeable, so you may want to interview her in addition to Nancy, just so you know your options.
If you have more specific questions, I can try to answer them or you can PM me, but I am SOOOOOOOOO happy we decided to homebirth. It made a huge change in my life for the better. Nancy was a big part of that, though one of the things I love about her is that she was my guide when/if I wanted her to be, otherwise, I was very much in charge and made the decisions, using her as a consultant. It was very empowering (the way it should be!)
SO, I wouldn't change anything about my births with her and I would choose her again in a heartbeat, were we to have another baby.
Best of luck!!
