What Our Patients Are Saying

My 3 year old has been in glasses for 2 years now and I recently had to find him a new optometrist. We came to Dr. Christian and I can’t say enough good things about this practice.

Can't say enough good things about Ophthalmic Associates and Dr. Sieber! She is truly a gem! Completed my final cataract post-op appointment today. All is great! Dr. Sieber, the office staff, and the surgical staff are professional, efficient, and AMAZING! They could not have treated me better. I highly recommend them for any eye care needs. Would not go anywhere else. - Nancy Straub
