About Us

middleburg-eye-signDr. Charles (“Chip”) Stine  founded Middleburg Eye Center in 1989.  A native of  Middleburg, Dr. Stine wanted to bring comprehensive eye care to those in his hometown who previously had to drive at least thirty minutes to get care.

When you visit the office, you’ll know it’s different! Housed in a log cabin that dates to the 1700’s, Middleburg Eye Center is not your typical doctor’s office. The staff strives to make you feel at home and comfortable, complemented by the warm, cozy setting. While the building may be from years gone by, the technology is current and state of the art. The doctors at Middleburg Eye Center continue to stay abreast of the latest treatments, techniques and options in eye care. Along with a lovely location, you’ll also receive the best in comprehensive eye care for you and your entire family.
