Dr. Guillory's work on and with me was simply exemplary! And Beth, the Technician, Crystal, one of the office girls, and the other Receptionist were very kind, patient and helpful toward me also. Dr. Guillory patiently listened to me, was concerned with all my concerns, and wanted to do the very best she possible could to help me. She thoroughly examined me two ways, to determine my correct needs of treatment. She not only examined and tested my vision capabilities and most current prescription glasses, and discovered how it could be could be improved upon with corrective lenses, for both distance and nearer ranges, but also carefully examined the structures and conditions, etc. of and inside my eyes. to determine their actual state/s of health, along with any possible changes that may be/have been present since my previous examination in 2015, and put all the evidence together, for her final hypothesis of my vision health and needs, based on the facts she discovered. I would HIGHLY recommend her services and treatment/s, and the rest of the staff at the Carbondale SIU branch of Marion Eye Center.
