This is by far the best vet I have found in a long time.

Dr. Lancer is great and the staff was wonderful. They were very patient and caring with my senior cat who has severe vet fear/aggression. They took the time needed to treat her nicely. While working on a plan for her they continue to be more than caring and helpful. When my cats results came back he took his time to explain everything to me knowing how hard it is for pet parents. Highly recommend. Very appreciative to them for their kindness.

Since I got Violet a yr and a half ago they have always taken great care of her. She went in for dental surgery today and they called and gave me updates and made me feel at ease. They sent me home with a full write up on details of her surgery and how she responded. The staff and Dr were amazing, kind and courteous

So happy with our kittens first ever veterinary experience with DR. Hammer as well as her assistant and LVT. The hospital was super clean and organized. They took their time to communicate with us about our kittens health and made their first experience stress free. I highly recommend oyster bay animal hospital!

My pup was very sick and I did not have a vet established in New York yet. When I called, the receptionist was very welcoming and told me to come as soon as possible and they would find time to help us. When I arrived, I did not have to wait at all and the technician was took a very thorough history and translated this well to the doctor. Dr. Lancer is everything you want in your veterinarian!
