Always a great experience whenever I am at Sight MD. I saw Dr John Passarelli today and I wasn't t disappointed in how i well I was treated at Reception, Carolyn the intake staff member who checked my vision preliminarily and Kevin who checked at another level so as to determine if my reading glasses prescription had changed since my vision check up a year ago. And it had. I also was pleased with my visit with Dr Passarelli whom I regularly see for routine vision checkups. You will not be disappointed in the care with which your treatment will be administered and how carefully notes are taken with your vision concerns. A world class facility for your vision needs!!
