About Green Valley OBGYN

Established over 70 years ago by Richard Dunn MD, GreenValley Obstetrics, Gynecology & Infertility represents one of the oldest and most respected medical practices in the Triad. The practice has now grown to seven board certified Ob/Gyn physicians with 200 years of combined experience in caring for the healthcare needs of the women in our community. The group also has extensive experience in the management of both high and low risk pregnancies after performing almost 25,000 deliveries. As important as experience, is the group’s dedication to continued training and education with all members now using the latest minimally invasive surgical techniques and advanced laparoscopic and hysteroscopic surgical methods to solve many gynecologic problems that formally required major surgery.
