DaNay: Optometric Technician


As our Optometric Technician, you will meet DaNay during the pre-testing portion of your exam. This is the perfect position for DaNay as she is very patient and friendly. After pre-testing, you will feel like you’ve known DaNay for years. A welcome addition to our office, DaNay brings a fun sense of humor as well as a caring nature. On her personal time, she is a wife and a mother to 7 ( YES!! 7!!!) children. DaNay brings her sense of family with her everywhere she goes. DaNay contributes to her community in her off time, often participating in walks for charity and collections that aid the homeless.

David: Lab Technician


David is the man behind the machine. Often seen but never really heard, he operates our lab equipment. He also is the quality inspector with incredibly high standards. David makes sure the orders are correct as well as meet and/or exceed our patient’s expectations. David takes pride in the quality of work our office puts out and wants to make sure even the insurance labs are held to the same standards. Although he takes quality and craftsmanship seriously; David is funny with a quick wit that keeps us laughing. When David is not fabricating custom eye-wear for our patients, he can be found surrounded by his wife and children “His favorite people in the world”.
