Instead of identifying each staff member individually, they can be recognized as part of our Performance Vision Care team. Each team member utilizes their expertise to achieve our overall mission for each patient. Our front office staff members can assist you with appointments, insurance verifications, and answer general questions.

Our dispensary staff members are licensed opticians who can assist with frame and lens selections, eyewear measurements, frame adjustments and repair, contact lens dispensing, and contact lens insertion and removal training.
