I just had a baby boy delivered by Dr. Yen. Throughout my whole pregnancy he was very caring and took time to help me understand any process. My first child was delivered by Dr. Chu which is great and my second boy was delivered by Dr. Yen. There’s hardly no waiting time in his office. you’re basically in and out within 15 mins. The delivery went very well and the recovery is going smoothly. He’s a great doctor.
