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

We have been bringing our loved pets to Oyster bay animal hospital for years now every doctor and staff member is amazing. I typically see Dr. Lancer he takes the time at our appointments to talk about solutions or treatments and always answers any questions I may have about anything no matter what! We really appreciate all the doctors and staff and highly recommend them to anyone looking to bring there pets to them!

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!
