Coronavirus Update

Our offices have reopened with a reduced schedule.  We are currently accommodating patients that were scheduled prior to the shelter-in-place order.  We will schedule all other patients in the next available appointment slot.  

Please remember to wear your face covering while at the office as mandated by state and county health officials.  Patients arriving for their exams will also have their temperature taken.  Anyone with a temperature above 100.4 degrees will need to be rescheduled.  If you have an appointment, but have not felt well recently, then please reschedule.  There is no penalty or fee for rescheduling an appointment.

In order to improve social distancing we are not allowing companions to accompany patients into the office.  If the patient is a minor child, then a parent may come in with the patient.

We are taking extra steps to reduce the risk of spreading coronavirus.  This includes using masks and breathing shields, sanitizing rooms between patients, providing unused or sanitized pens, making hand sanitizer or hand washing available to patients, and sanitizing eyeglass frames in our optical departments.

We're grateful to be back and helping you with your vision care needs.

  • "Dr. Trejo is serious but is very knowledgeable, he took the time to explain details to me. They dont have a huge eyeglass selection for designer frames but are willing to order anything for you. Their prices are very reasonable as well, alot cheaper than most places. I would totally recommend Dr. Trejo to anyone looking for an Optometrist."
