★★★★★ I just want to take a moment to say how stellar the doctors and staff at companion RN have been to our sweet Teddy since the first day we took him in. Dr. Courville has been a pleasure to work with. She is so kind and very knowledgeable. It's evident she has a big heart and truly cares about her clients and their pets.The clinic staff are always so gentle and kind to their furry clients, and most even remember our pets name upon arrival (a very special and welcoming touch). On top of that, the providers and technicians, despite being so busy, always make time to answer my (anxious cat mom) questions, and that means a lot to me. Very appreciative of the care Teddy has received at Companion.Sahar E.Sahar E. ★★★★★ Cosmo, Dr. Bryant and Alex truly exceeded my expectations. They were so accommodating to the time our pet needed to be seen. They were gentle, calm and very thorough with the exam. Dr. Bryant/Cosmo explained everything and was sooo helpful with the treatment of our pet. Overall wonderful experience.Celine G.Celine G. ★★★★★ My normal vet cancelled my international health certificate appt day of and Companion Animal Hospital was able to not only schedule me a same day appt due to urgency but also make sure everything was in order. Dr. Kaya Bryant was wonderful, knowledgable and great with my pup. We were impressed with their service and cleanliness. We also appreciated the entire staffs' willingness to help us and understand our needs. The vet techs and front desk staff were also knowledge with their services and friendly. Additionally, communication throughout the process was fantastic. We knew where we stood each step of the way, knew what was needed and they answered any questions. Last thing to note is they are accredited by AAHA. We will definitely be coming back.Dezzarae Arce (.Dezzarae Arce (. ★★★★★ Brought my Golden Retriever into the office for his first visit at Companion River North and we were welcomed and they have soft music playing, excellent exam rooms, very clean and comforting. Dr. Bryant was amazing and made Beans so comfortable that he rolled over on his back for a belly rub. Results were back quickly! I highly recommend Companion River North.Colleen B.Colleen B. ★★★★★ The veterinarian doctor that saw my dog was amazing, she went over the medications my dog needs in great detail, she gave me a list of shots and test to keep up with, for my dog and my dog liked her from the start. It was our first visit and we will be a family now. Clean facility and great friendly staff.Lorettajean /.Lorettajean /. ★★★★★ Quick and easy appointment with very sweet doctorsSuper recommendFabiana A.Fabiana A. ★★★★★ Snowball has gone to Companion Animal Hospital DayCare for her 3 years.

They make memorable moments that add up for Snowball 🙂Nancy Ann D.Nancy Ann D. ★★★★★ Dr. Courville and her team set the standard for animal care. I have seen a number of Vets for my dog Peanut and the care he receives from Dr. Courville and her team is second to none.Howard G.Howard G. ★★★★★ Great vet! I appreciate that they were able to see Butter same day and give her medicine so she could start feeling better. They were so sweet when she kept having accidents on the floor. Thank you for making her feel so comfortable!Lauren Van S.Lauren Van S. ★★★★★ After a week from hell and my dog getting attacked by another dog, they saw us quickly and were incredibly helpful. When our dog tore his acl in the same week, we got treatment right away and now have a plan for treatment until surgery. My sweet boy goes into the vet without fear now and is comfortable with the staff here. If I could give more than 5 stars I would. Thank you all at companion for such a wonderful experience!Madi Q.Madi Q. ★★★★★ I brought my new, very young rat, Rocky IV, in for his first appointment last night, and right off the bat: from reception to the technician to the doctor herself, everyone at CAH was friendly, caring, and knowledgeable. And to Dr. Archer (if you ever see this): I cannot thank you enough, once again, for your kindness, compassion, expertise, and love for the animals you care for. I know Rocky felt adored by every member of the staff, and as a new rat owner myself, I know we're both in exceptional hands.AND they're only a ten minute walk from my apartment, so yeah: absolutely flawless experience.Keenan M.Keenan M. ★★★★★ I am a new cat mom and I was very nervous about bringing my cat in without my mom! CAH took very good care of Franklin, got him the tests and wellness check he needed, and made sure he felt safe. I couldn't have asked for a better vet.Alyssa H.Alyssa H. ★★★★★ Our dog had heart failure and had to be put down. This was absolutely devastating and the staff here were incredibly sweet. I was unable to pick up his paw prints for 2 YEARS because it was so incredibly painful. We finally mustered up the courage and they HAD THEM AVAILABLE! They saved the prints for two years! I AM SO GRATEFUL for them to have saved these pawprints for so long. It was SO HARD TO FACE but they made this transition a lot easier. I can't thank everyone enough. This means more than you will ever know!Ashley DAshley D ★★★★★ Dr. Archer and her staff were wonderful!! The front desk staff were polite and helpful.

We did not have a vet after moving to the city from the suburbs. My Cocker Spaniel has a problem with his eye that turned out to be primary glaucoma.

Going to the vet is stressful for everyone involved and when I arrived they made me feel so relaxed. You can just feel their love for animals the minute you walk in. My vet tech was fabulous! So much energy and was really amazing at explaining some of the options to keep my cat healthy. The doctor was professional and I trusted her feedback and recommendations. I plan on taking my cat back for her annual check ipa and any emergencies.Michelle P.Michelle P. ★★★★★ Companion Animal Hospital was able to get my rabbit an appointment right away. I called three other exotic animal hospitals and no one had appointments available. The staff and Dr. were wonderful!!! They really care about the animals they treat. An assistant called me the next day to see how the rabbit was doing and to make sure she was ok with her medication. I highly recommend this hospital!!!yvette Z.yvette Z. ★★★★★ We have been taking our 6 mo puppy to Companion since we got her and are so happy we do!

I would highly recommend Companion to anyone looking for a vet.Veronika G.Veronika G. ★★★★★ Everyone at Companion has always been very sweet! They are all down to Earth and are really accommodating.Alexis F.Alexis F. ★★★★★ My dog’s normal vet unfortunately moved away, so I had to find a new vet for my dog. He had a large growth in his mouth, so I was trying to find a vet that would take him as soon as possible because the emergency 24/7 vet wouldn’t take him. I was referred to this animal hospital and they couldn’t have been nicer. From the person who took the appointment, to the woman who walked us out after my dog’s appointment. I highly, highly recommend this animal hospital. They took such wonderful care of my dog and were very nice. They understand that your pet is your baby, but understand that people have a budget. Everybody here are definitely animal people. As a dog mom, I felt like I was able to trust them with my dog, which isn’t always easy! 10/10.Katherine B.Katherine B. ★★★★☆ This morning we brought our cat for her nails cut. The tech’s were great the service was good. I was very happy with Campanion animal hospital.

I get the sense they geniully enjoy taking care of pets. The location is quite convenient for me as well.James YJames Y ★★★★☆ Nice to have a vet in the neighborhood, currently bringing my OLD dog here. Sometimes I feel they are trying to oversell (acupuncture therapy for arthritis), but the staff at every level is always super kind and gentle. My poor old man gets very nervous but they are always prepared with the peanut butter and he has always received excellent care.Megan S.Megan S.js_loader
