Extremely friendly, knowledgeable, and professional. The entire staff is very welcoming and efficient, but most importantly, I have observed their willingness to "go the extra mile"--- not just for me, but for all their patients. My appointment experiences have been ones with little to no waiting time. I recommend the Karns Vision Center to others any time there is an opportunity to do so! The doctors are excellent and I appreciate their sincere and caring interactions with their patients and staff, no matter how busy they are!
