Dr. Jeung Choo Yoo has been in private practice as an OB/GYN doctor since 1978. At his office in Banning, California, we accept patients with any gynecology, obstetrics, or birth control needs. We have been in business for more than 30 years. Over that time, many of our patients have returned to us regularly and even gone through multiple pregnancies with us. They refer their loved ones to us because they know they will receive the best care here.
