  • I was recommended to Dr. Eric Donnenfeld at OCLI in Long Island by another Ophthalmologist. My experience in that office tells me that I was recommended to the right place. This is a place where 2+2 is always 4. I mean to say that the appointment is on time and the wait is very minimal compared to other offices where appointments are made back to back with the result of patients waiting and waiting reading books and watching movies. Money is important but putting money-making in front of profession like a business is like putting the cart before the horse. The staff is very curteous, cautious and they even remind you of upcoming appointments. They display professionalism and they know fully well what is going on. The remedies I have received from there so far has been very encouraging and invigorating. I will whole-heartedly recommend this place to anyone. Wish Dr. Donnenfeld and his efficient staff the very Bestest. 👍
