THE most professional optometry office experience in my many years of having eye exams! Front desk,... technician, doctor… all competent, knowledgeable, personable people. The exam itself was most comprehensive; Dr Best took her time and was thorough in both treatment and explanation of her findings with regard to my particular eye care needs. I highly recommend this practice!
