I chose to train with DONA for the referrals and structure of the organization. It was important to me that I have hands-on, in-person training, rather than distance education.
My DONA training was held in the yoga room at a healing arts center with all of us sitting around in a big circle and a very casual, flowing model of teaching. My trainer was also a CBE and she spoke often of home birth, including a class she had just taught to three home birth couples. So the PP's experience is not the only possibility with DONA, it certainly depends on the trainer, I think.
Also, DONA allows TWO years to complete your requirements, and you may request an extension if necessary.
I thought the quality of the training was fine, but since I was already an experienced CBE and had attended births for awhile, I really just went through it as a formality to get some credentials behind my name. I'd be interested to take an ALACE training sometime as continuing education but would not be interested in certifying with them, as I wouldn't see the benefit (not a big referral source, and their internal structure and customer service right now are shaky, it seems).
OnlyAngil, meet me, meet me!

I'm DONA certified and I'm collaborating on a birth right now with an awesome CAPPA trained doula. I'd never dream of suggesting she re-do her training, she's great.
