MEET OUR TEAM
Together Everyone Achieves More
At Omni Vision Care delivering value to our patients has always been a group effort. You are greeted and checked in by one of our capable receptionists, assisted and screened by an optometric technician before you are seen by the eye doctor. At the end of your exam, an optician will walk you through the eyewear options. If you need prescription glasses, they are edged and sized by a technician at our in-house lab.
