A Legacy of Eye Care in Quincy: Our Focus Is You

Site Vision Center has been part of the Quincy community since 1955, built on a simple idea: eye care should feel personal, not rushed. From our earliest days under Dr. Frank Gianfriddo, O.D., to our current home at 33rd and Broadway, we have remained focused on delivering thoughtful, quality vision care to patients throughout the tri-state area.

Today, we continue that tradition with a modern approach to eye health, combining experienced providers, innovative diagnostic technology, and a strong commitment to patient education. Every visit is designed to give you time, answers, and care that is tailored to your needs.

From comprehensive eye exams and children’s vision care to dry eye treatment with OptiLIGHT and diagnostic testing, our clinic is here to support your long-term eye health at every stage of life.

A Family Legacy of Eye Care

Site Vision Center is built on a long-standing family tradition of serving the Quincy community with trusted, personalized eye care.

Dr. Ray Gianfriddo, O.D., practiced here for decades after graduating from the Southern College of Optometry in 1977. A Quincy native, he dedicated his career to caring for the community he grew up in and is now retired. His work helped shape the values and patient-first approach the practice is known for today.

That legacy continues with Dr. Joe Gianfriddo, who carries forward the same commitment to thoughtful, personalized care and long-term eye health for families across Quincy and the surrounding area.

Meet Dr. Joe Giangriddo

Dr. Joe Gianfriddo is the lead doctor at Site Vision Center and has been a valued part of the practice since 2014. Born and raised in Quincy, he completed his undergraduate studies at Quincy University before earning his Doctor of Optometry degree from the University of Missouri College of Optometry.

Dr. Joe is a member of the American Optometric Association and is dedicated to providing thoughtful, patient-focused eye care for individuals and families throughout the community. His approach emphasizes clear communication, education, and taking the time to make every patient feel comfortable and informed about their eye health.

He is supported by a skilled team of opticians, technicians, and administrative staff who share the same commitment to delivering attentive, compassionate care to every patient who walks through the door.
