I don't know but try the International Cesarian Awareness Network. www.ican-online.org Phone number is 1 800 686 ICAN. She can join their email list also.
I know a friend of a friend who recently had a VBAC at Holy Cross in Wheaton or Olney. It seems hit or miss though. Apparently her usual OB had her scheduled for a repeat c/s for no good reason and she went into labor before the scheduled date and luckily another OB was on shift and encouraged her to try to VBAC.
