I had a very concerning issue come up with one of my eyes this weekend and no ophthalmologist offices were open. Dr Cohen had an emergency line and called me back in person to discuss the issue! He made me feel better about what I was experiencing and was even willing to see me today if necessary, but based on our conversation told me we could wait until Monday- he doesn't have all these great reviews for no reason- excellent customer service and willingness to go above and beyond!!! I don't write reviews often, but I felt I needed to this time.
