Dr Walker has been wonderful. He made sure I was informed and understood what was happening with TTTS and the urgency if needing to get in for surgery asap. He was comforting and I feel like he genuinely cared about my babies and I, he took the time to talk through the procedure and answer my husband and It's questions both before and after the surgery. I couldn't ask for a better Dr!

He was wonderful, and its really so nice to have a smiling, positive doctor. I've always gotten excellent care with EMFM. I'm thankful to them and God.

I wouldn't have wanted to have any other doctor. Dr. Walker was fantastic for not only me & my husband, but for our families as well.
