They were a lot cheaper and a lot better service then anywhere else I went. I Went to one vet and they made me wait about 5 hours and wanted 400$ and had no information on the problem they said I needed another 1000$ to run test but weren't sure if they'd tell me the problem went here and for 200$ did what the other vet wanted 1500$ for. Sager was way more helpful and showed they cared for my dog.

Doctor Sager and the whole team at Sager Animal Hospital are incredible. They always make sure to give you a quick call back when you have questions. They are patient and kind and I feel confident my pets are in good hands. With my older dog who is presently ill, Doctor Sager and the team have been so wonderful - they have answered all my questions and are incredibly compassionate. He has been the vet my family has gone to for almost 20 years.

I have always liked the way Dr Sager and his people treat my pups. He is up to date but is more like the vets of yesteryear. He listens to his patients and the way they are acting

It's a shame Dr. Sager has such an unpleasant wife, because I really like him. Unfortunately, because she has repeatedly made going there unbearable, I was forced to go elsewhere. Pauline resents customers that have gone elsewhere.heard of second opinions? Gave me the choice after being a 13 year customer to leave a credit card number on file or go elsewhere! Just saw Dr. Sager yesterday that went as well as always when Pauline is out. She blamed Dr. Sager for making an appointment without paying first! She needs a personality transplant. Reminds me of the Soup Nazi on Seinfeld.

Dr Sager is fantastic. He is kind, knowledgeable, and takes his time to ensure you and your pet feel comfortable. He doesn't put you or your pet through any unnecessary tests. We have been very happy here.
