It’s pretty amazing how a pet can touch your heart and change your life. These special little creatures ask for nothing in return yet give so much of themselves. They’re our biggest cheerleaders, our fiercest protectors, keepers of our secrets and givers of unconditional love. For most of us, they’re more than just animals. They’re part of the family.

At Saint Francis Hospital for Animals of Sayville and Oakdale, we understand the bond you share with your four-legged companion. In fact, it’s that same connection we share with our own pets that inspires us every day. It also allows us to relate to you and your pet on a more personal level.

Our mission is to provide exceptional medical care in an environment that feels safe, comfortable and homey. Unlike other hospitals that emphasize technology and modern treatment options, we believe these things come in second to a warm, personal touch. Our honesty, integrity and genuine love for animals have kept generations of pet parents coming back.

We could spend hours telling you how different we are, but we’d much rather you experience it for yourself. If you’re looking for an Oakdale veterinarian that will truly care about you and your pet, come give us a try!

    This place blows Oakdale Veterinary Hospital out of the water. Friendly, caring and everyone is so sweet.
