M.V.
I am so sorry about your birth experience! it sounds aweful, and it sounds traumatic. Having had a horrible on call dr. too, a bit of a traumatic experience in the hospital myself, and an infeted cesarean scar, I can totally relate to the fear, and the anxiety of another pregnancy.
That said, I would recommend Dr. Harter, in the summerlin area, or Dr. Juarez in Henderson. I am not sure about the insurances though. They're both very caring.
Have you also look at the options you want for your cesarean ? there's resources online for a 'family centered' cesarean, and the local ICAN chapter can also give you some. you can find them listed on the www.birthyear.net website, under "international cesarean awareness network". I'm M., the Librarian for the chapter.
also, if it helps any, www.plus-size-pregnancy.org has great resources on emotional healing after a traumatic birth, and there's also a book called "rebounding from childbirth".
good luck, best wishes, and huggs.
M.
