    Dr. Heller is a wonderful compasionate vet that truly saved my puppy’s life! Wasn’t sure I wanted to keep a sick 8 week old 9 lb German Shepard but now my Chase is 5 months old weighing in at 54lbs! Thank you so much Dr. Heller for your help in getting Chase better so we could take him home!

    My puppy, Hundo has received excellent care from all the staff at the Westhampton Beach Animal Hospital! They love him and make all of us feel welcome! The doctors are friendly and can always answer my questions (As a new dog mom, I have a lot!). We will continue to trust them with caring for our puppy!

    Rachel L.

    I have been taking Stumpy the Rock Star here since he was 6 weeks old. He loves to go there to see all the wonderful staff and Dr Heller. I have him groomed there as well because he likes to be with all his friends who are so good to him. Recently I tried boarding him there overnight and I think he wanted to stay longer. This is a wonderful place to have care for your pets.

    Went in to see Dr. Heller with my dog late on a Saturday. Most of the places around were closed. He graciously took us last minute and took excellent care of my dog. Highly recommend this hospital.

    Jared C.

    Excellent, professional, compassionate, dedicated. The doctor was willing to use an injection needle to draw a urine sample from the floor after my dog had an accident, amazing. He wanted to make sure to get everything to test to confirm what could be wrong. Called the next day with results, spent time on the phone answering all of my questions.
