They have multiple locations throughout the city.Brenna W.Brenna W. ★★★★★ This was my first time visiting and I was so pleased with the service my dog received.

The doctor and all the staff were really great. They were attentive to my concerns and questions and were happy to answer everything. I never felt like they did not have time for me or my dog. They were very patient and caring with my dog as well.I also found the costs reasonable. Everything was great!Brad KBrad K ★★★★★ very grateful we’ve found this place. The staff at this location is kind and helpful, and Dr. Kung has been a blessing to our Bella (and to us too!) She has been amazing with our fur baby on multiple occasions. Our dog suffers from severe separation anxiety, and they created a treatment plan to help her receive the care she needed while ensuring she was as comfortable as possible. Bella is doing great after her appointment today, and i’d recommend her to anyone seeking care for their pets.Thank you again to everyone who has helped care for her! 🙂Destiny M.Destiny M. ★★★★★ I recently adopted a bully mix breed pup and decided to get him checked out and up to date on shots. I did my homework on this place and after bringing my dog here I was not disappointed. When I made the appointment I explained to the call taker that my dog is known to be dog aggressive so that the hospital would be aware before I brought him in.The call taker explained how they handle these situations and that I should call when we arrive to ensure there are no other pets around for pet safety.This is exactly what happened, I arrived and was greeted by Jocelyn who was understanding of my dogs personality and took care of us great. She got all of our information and answered all my questions.Dr. Schoessow came in and again was very understanding and knowledgeable about my dogs situation. She was very professional, explained all the procedures that would be done that day and answered all of my questions. I was very pleased with Dr. Schoessow and her staff.Adrian Z.Adrian Z. ★★★★★ Dr. Kung and staff (tech, Jocelyn) were amazing with our Arthur Fonzarelli. We've had 4 moves in under 2 years and Fonz was recently diagnosed with Chronic Enteropathy during our move(s).Everyone at Companion was helpful and welcoming, while also ensuring that Fonz was back on his preventatives and up to date. Dr. Kung is warm and collaborative. Same goes for the staff, from scheduling through to the end of our visit.I cannot thank them enough. Now that we are settled, I feel we have finally found our new "home" vet clinic. Smaller office. Quaint and comfortable.JP B.JP B. ★★★★★ Parking lot vet visits will never be ideal, but the vet and staff who work at this office are great communicators who ensure you leave with all questions answered. They are transparent about pricing, calling for approval of a line-by-line estimate at the start of each visit. They also use tech well -- email reminders and web forms for scheduling and completion of pre-visit questionnaires.Charlotte W.Charlotte W. ★★★★★ My dog, Coral, loves going to the Vet. She runs in and gets hugs and gives kisses. They take great care of her. She would stay there all day if I didn't come to pick her up right away. The tech called me and let me know everything went well and Coral was laying down on the floor cooling off. Coral is a Labrador Retriever.Theresa M.Theresa M. ★★★★★ Took Jimmy to the vet today as having issues. Love the staff, techs and vets. Very nice and helpful.Rick H.Rick H. ★★★★★ Great service from the staff and vet! Doctor and staff were very kind, insightful, and were great with the care they provided.
