They misdiagnosed my dog said he has an abscess and needed to be put asleep to drain it and took a sample under the microscope and said for sure that’s what the issue was. I didn’t trust the vet so I went to my vet afterwards ( my vet couldn’t see me same day so only reason I went to companion) and they did same test sent it out and it was a infection and gave us antibiotics within 4 days the wound was healed and he’s back to normal.no surgery required like I was told from companion that needed to happen. I will never go there again I spent 150.00 for them to misdiagnosed my dog.

Dr. Koller has been fantastic in treating my small dog. She has had eye problems recently, dry eye and conjunctivitis, and several months ago a bacterial infection giving her severe diarrhea. In each case, I simply described what I had observed and he examined her briefly and knew exactly what she needed. He was so gentle and loving with her and his many years of experience made the exam and remedy quick and easy. I so appreciate the service and Companion Pet Clinic which makes having a pet affordable for so many if us in Gresham, Oregon.

We took our dog in to get neutered and the quality of care was exceptional. Such a great team affordable pricing. I was also able to get medication for him for the 4th of July all in a matter of a phone call. Thanks for all your hard work companion pet clinic

Thank you for taking care of Luna’s tooth. The front desk ladies are very nice and helpful. They were very knowledgeable and kind. And there was not a shock when you went to pay. Thank you again!

All three Dr.'s are awsome. I know diagnosing a pet isn't always easy, but these guys do their best. Dr.Powers was very kind and compassionate when he had to put our boy down.

I went here with my grandfather to put his dog down. The two girls at the front were not very nice at all. It’s like they couldn’t read the room…. They’re clearly just here for the check and that’s about it. I get that this job could be tiring or stressful sometimes but if you’re not a compassionate person you should probably find a new career.

DO NOT GO HERE! Horrible experiance here while having my dog euthanized. One of the vet techs handled my weak old dog roughly to the point he was yelping loudly. When the actual veterinarian came back in the room with my dog he was completely limp and sedated to the point he didnt even look alive. They didn't tell me they were going to do that. The vet then quickly euthanized him. This was a serious problem for me how they handled the whole situation especially when i told them i want to be with my dog through the whole thing and I feel i didn't get to be with my dog in his last moments because of what they did. When i confronted them calmly about the problem I had they were very rude and told me that I'm a problem for having a problem. The vet tech i had the problem with wouldn't even speak to me and the rest of the staff were rude except one nice girl at the front desk. Vet techs and workers here are incompetent rude and careless! After doing some research I found this clinic has horrible reviews and the owner/ veterinarian has a bad reputation for animal abuse!! Lots of similar experiences here I'm reading. I'm very upset with the experiance i had here while going through one of the hardest times of my life putting my childhood dog of 16 years to rest.

Th vets are very compassionate, they amputated Otto's leg only after keeping a close eye on his compressed lung that had a air pocket next to it. But did a awesome job on the surgery.

Many years ago, we took all our pets to Companion Pet Clinic. It used to be a great and trustworthy clinic, Not anymore! They may be less expensive to walk in the door, but the care is substandard and very rude reception. I had a 5 year young dog who was diagnosed with a heart murmur. Companion prescribed a heart medicine but failed to give him a diuretic. My poor little guy's lungs filled with fluid and died. He would have lived longer with an added diuretic.

We have had the pleasure of taking our pets to see Dr. Z for the last ten years and he is the very best vet we've ever had. We travel 45+ min just to ensure our pets are cared for by HIM! 10/10
(I am not receiving anything whatsoever by posting this and I was not asked to provide a review.. he's just THAT great.)

I can’t say enough good things about Companion Health Clinic and Dr. Koller. After my cat, Kitter Boy, suffered a second urinary blockage in two weeks, we were devastated, scared, and unsure of what to do next. Dr. Koller was calm, experienced, and incredibly compassionate. He walked us through the risks, options, and ultimately performed a perineal urethrostomy (PU) surgery that saved Kitter Boy’s life.
The care we received here was above and beyond. Dr. Koller clearly knows what he’s doing. He was confident and kind, and I felt completely reassured knowing Kitter Boy was in his hands. The staff treated us with respect and kindness throughout the entire process, even when emotions were high.
We’ve been through a lot with this cat, and finding a vet we can trust is priceless. I’m truly grateful to have found this clinic and Dr. Koller. Highly recommend Companion Pet Clinic!
