  I was recently traveling when I had a concern about my eye. Dr. Groo and her staff at Hudson Valley Eye Doctor were so incredibly helpful. They went above and beyond to assist me. I was relieved to get such great support over the phone. They were responsive, professional, and genuinely caring for how I was feeling. (There aren’t enough doctors like that around anymore!) Their expertise was apparent and their dedication to help me and their patient care was evident. I am a regular patient at Hudson Valley Eye Doctor and highly recommend them for any medically related eye check-ups as well as any optometry needs. (They have beautiful frames too!) Thank you Dr. Groo for the exceptional service and helping be during my vacation!

  Horrible place. My husband had his first appointment on the beginning of April, and still today May 2º he didn’t get his glasses or contacts!!! He is very upset because he paid very expensive for all of that. The last 2 appointments he waited almost an hour to talk to the doctor for only 5 minutes.

  I was a long time patient of Dr. Kaknis. I'd visited him since I was a child, but I recently made the choice to never go back. I think there's a relationship between doctors and patients where you should be able to trust that they have your best interests at heart, and I no longer trust that Dr. Kaknis does. I think he and his staff are most interested in making money. Firstly, they push you to buy eyeglasses and contact lenses through them. This is kind of standard for most eye doctors, but also I've had them refuse to give me my prescription (even when it wasn't expired) because it was a few months from expiring and they wanted me to come in and be examined again. I ended up ordering through 1-800 contacts, who got the prescription from them with no issue. The biggest problem for me, however, is that I've been using Vertex Toric lenses for years. They cost about $300 for a six month supply, and for me that is not chump change. I visited a new optometrist recently and was told that these lenses are "legacy" and really not used any more. Furthermore, she prescribed me a new type of lens that (according to her) brings 6x more air to my eyes, so they can "breathe" more. Why would Dr. Kaknis continue to prescribe me these old lenses?? On top of that, my family goes to him still, and my mother just told me his staff lied to her about how much of the cost for glasses was covered by insurance. I don't trust this doctor or his office.
