How likely are you to recommend Dr. Barth?

(Select your rating)
With my old OB, my first child was stillborn late into the third trimester, and I almost lost my uterus, post-birth. For future pregnancies, I knew I'd be high-risk, and wanted the best possible care. I can't give enough praise to Dr. Barth, who helped us through an incredibly stressful, anxiety-producing second pregnancy. We will always be grateful to him. He made us believe that we'd one day be parents to a living child, and he made that dream come true this past January. By far, the best of the best MFMs.
