Meet the Clapp Optometric Centre Team
As Optometrists, we check more than just your prescription for eye glasses. We are eye doctors that specialize in detecting eye diseases. Many eye diseases do not have symptoms, but are treatable if detected early.
We are proud of the quality and scope of the many primary eye care services provided in our office. Our optometrists and staff care about you and your family, and about your eyes. We believe in staying current with the latest technology, procedures and products.
