I would highly recommend Dr. Samuel Chantillis for fertility issues and then Dr. Ted Fogwell for your OB/GYN, both at Presby Dallas on Walnut Hill.
Dr. Fogwell was so wonderful with me while pregnant with my twins (but deals with many high risk pregnancies). I had 3 miscarriages before and Dr. Fogwell was so compassionate throughout my whole pregnancy. His staff are great, too. Someone will always call you back or see you ASAP if you have any worries. That sense of ease helped me tremendously throughout my pregnancy. My twins will be 2 in May! They also work with a great prenatologist, Dr. Reinhart -- all are in the same building, so if you need to go from one to the other, it is easy and they communicate great together.
If you prefer a woman, I have heard Dr. Haygood at Presby is wonderful, too.
Best of luck and let me know if you have any further questions. You can find their numbers here: http://www.texashealth.org/body.cfm?id=952
