​​​​​​​One of Dr. Joanne Myung's biggest passion is working with children. After receiving her OD degree from SUNY optometry school, she received extra training to become a Fellow of COVD (College of Optometrists in Vision Development). This fellowship allowed her to become more knowledgeable and competent in developmental vision in children as well as binocular vision in children and in adults. It is imperative for children to have a comprehensive eye exam before starting school to ensure their eyes are ready to learn.

Dr. Joanne lives in Los Angeles with her husband, and two beautiful children. When she isn't busy running around with her kids, she enjoys cooking, playing tennis and taking a nice stroll at the beach.
