Dr. Dionisio took care of my Aja for 12 years. When he diagnosed her with a splean tumor, he insisted I go to an emergency hospital where we had to put my sweet baby to eternal rest.

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

My family and I have been taking our dogs to Dr.D for over 17yrs and I can not possibly stress how wonderful this veterinarian is. To say he's amazing would be an understatement. Incredibly knowledgeable, caring, compassionate, thorough, reliable and VERY FAIR WITH PRICES are just to name a few. He and his staff genuinely care for your fury friend as if they were their own. I'm truly going to regret the day dr D retires. DON'T!!! Love you guys so much and thank you for taking care of Alete, Bael, Zoe, Zoey (yes, two Zoey's lol) and Sofie ❤

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.
