    Don’t have enough good things to say about Companion, especially Dr. Sweeney. Our dog, Bruda, had UTIs repeatedly & Dr. Sweeney & Dr. Marrinan were the only vets to actually investigate further and take our concerns seriously (& we saw at least 5 vets prior)! Our dog is now healthy & happy thanks to Companion. We are so thankful for all the guidance & support they have provided the past few years!

    We want to express our heartfelt thanks to the incredible veterinarian, Dr. Marrinan ,who has gone above and beyond for our pets. We are truly impressed and deeply grateful for his dedicated service to our dog and cats. His compassion, especially for feral cats needing help, is truly inspiring.
    He understood the struggle of trying to treat and take care of animals that are untouchable and made it so much easier for me to help control our uncontrolled cat population!

    I brought my cat in this morning for some illness concerns and it was our first time visiting. We saw Dr. Lizzie and her nurse Zari. They were both AMAZING! They took such gentle care with Cinnamon and took the time to explain everything to me. They were so patient and answered every question I had. Cinnamon also was very calm and gentle with the Dr. and nurse, so I know she felt comfortable and safe. I highly recommend Companion Animal Hospital and most especially Dr. Lizzie! Thank you again for taking such great care of us!
