Our Doctors

The professionals at Emery Eye will help you see better and in many cases can enhance your academic, occupational or recreational performance through comprehensive eye care. Common eye problems develop gradually over time and unlike the rest of your body, your eyes rarely hurt when something is wrong. In fact many people suffer from poor vision for years before realizing they have an eye problem.

Emery Eye Center uses the most advanced instruments and procedures to evaluate the health of your eyes and prescribe the appropriate eye wear, contact lenses, or other treatments to help you see your best.

Meet your eye care team.

We are here for you.
