Luckily I have not had to deal with endometriosis, but I do know of an OB/GYN that is absolutely most wonderfully fabulous, Dr. Norwood. My co-worker pointed me in his direction when, in the middle of my first pregnancy, I became extremely ill and my current doc was doing nothing. Another co-worker went to him for pre-menopausal issues and fell in love as well. He was in Dallas' best Doctors magazine a few years back and a large portion of his clients are also doctors. The unfortunate thing is that his practice is at Baylor- downtown Dallas. But I promise you it is worth the drive. I now live in Aubrey and gladly make the over 1 hour commute. His practice is called Woman's Health Alliance.
Let me know if you need more info. I promise this doctor will take excellent care of your daughters!
