We started seeing Dr. D and his team in 2002. My puppy at the time had asthma; for the first few months of her life, other vets told us they did not know what was wrong with her, even after spending thousands of dollars. But after just one time of visiting Dr. D and getting the correct diagnosis, my baby girl lived to be 19 years old. We continue seeing him now. He is great and really knows what he is doing. Great service. Would give more than five stars!

My family and I have been bringing all our fur babies to Dr. D since 1989. He is extremely compassionate and knowledgeable. He is honest and cares more for the fur babies than dollar signs. I truly do not know what I would do when he retires! The girls always try to accommodate and are very sweet and good with the fur patients. The office can use some updating but that would not deter me from bringing my fur baby to Dr. D

The best! Hands down the best! I will legit be lost when Dr. D retires. I been taken my dogs to him for close to 30 years. He is caring, compassionate and knowledgeable. Words cannot express what a saint this man is. In addition, the staff there especially the main women whose name I forget is fantastic!!! Please never close and thank you from bottom of my heart staying open all throughout covid.

About us

Annadale Veterinary Clinic has been serving the residents of Staten Island and their pets for over 40 years. Dr. Dionisio and our caring staff treat each patient as part of their family.

Our practice strives to deliver high quality medical, dental and surgical health care. To assist in this objective we offer a wide range of diagnostic testing such as: EKG, echocardiogram, sonogram, and digital x-ray. We utilize a licensed veterinary laboratory for all blood work, cytology and pathology.

We value your observations and integrate them with our clinical findings to formulate an effective treatment for your pet.

Annual preventative care will help your pet live a longer, healthier life. A physical examination, with blood work when indicated, may detect incipient disease. Early intervention may prevent a problem from becoming serious. A wellness visit also ensures that your pet’s vaccination, heart worm prevention, and parasite control treatments are current.

It is our goal to help you provide a happy and healthy life for your pet.
