When I had an emergency with an eye injury, I was worked right in immediately. I really appreciated that since I was so concerned that I might have damaged my Toric lens. Previously, I have been seen right away with other eye traumas. Thank you to all who facilitated that.

I have always had a great experience. All my procedures and conditions/treatments are always explained to me in detail. Dr Kavanagh is very kind and caring and his staff is very well trained and professional.
