K.H.
Dr. Samuel Chantilis at Presby Dallas on Walnut Hill. Almost everyone I know who's used him has had success, he's nationally known. I have a friend who tried IVF 3x unsuccessfully with another doctor and then went to Dr. Chantilis and has a little boy. I've also heard that the doctors in practice with him are very good.
Oh - and I was a patient as well. Had a daughter with no problems at 38 and then had 4 miscarriages before I went to Dr. Chantilis. And now we have twin girls.
