My doula was jill richards. I interviewed a few and she was the right one for me. You can also go to the certified doula website (I think that's what I googled) and find a list in the Knoxville area.
If you are on Facebook, consider joining the group "Peaceful Parenting Families of Tennessee." There are a lot of Knoxville area mamas in it and I am sure they could point you towards some truly great doulas!
