Any Doulas in the Phoenix area?

I really didnt realize there was a common thread theme of doulas lately, but that doesnt deter me from posting my question . Im currently an LPN, and also an RN student. I have a history of working in a Maternal Fetal Medicine office, which made me realized I absolutely want to work in L&D. My passion is for the laboring mother (and of course successful delivery of the baby). While in school, Im wondering if any doulas in the area have ever accepted a nursing student to volunteer to assist them. If there are any doulas in the area that would be receptive to that idea, would you please either PM or respond back. I think it would be a wonderful educational experience. Thanks for any responses.
