Extremely poor bedside manner and they cared less about my pet than any vet I have every been to.

This is the most amazing care I’ve ever received. In about a month, we brought in two cats. The first didn’t need to be seen, and as we had only spoken with a tech, we were refunded the initial deposit for being seen.
Two weeks ago, we brought Nova in due to lethargy and looking overall ill. Before I even started signing in, they took her back. Once in the treatment room, they explained everything that was going on and why they were wanting to do each test or treatment. They had to keep her overnight for a blood transfusion, and the overnight vet called early in the morning to update us and let us know who was coming in next and what we should expect. We finally brought her home, and she seemed happy and better than she had been. She didn’t look scared or upset, which is such a relief.
Tuesday night, she began collapsing under her own weight and wouldn’t eat. Wednesday, we tried to get her in to our primary, who couldn’t see her, and ended up bringing her back here. Once again, they took her before we’d even finished checking in, and we were brought into an exam room quickly.
They came back in, and told us that there was nothing left for them to try, and that it was time for her to rest. They brought her in, let us love on her, and even came in to explain the cost and to let us pay privately in there rather than in the lobby. Nova was put to rest on 9/9 at 9:06am.
From check in to check out, everyone was extremely compassionate and informative. There was nothing they did that they didn’t explain why they were doing it, how the process would go or how long for results. They treated us, and Nova, like their own family. I, hopefully, will never have to come back, but if I ever need emergency care again this will be where I go.

Awful! My dog had a 105 fever. Didn't treat the fever, gave her fluids and something for nausea??? Didn't miss a beat offering unnecessary scans and xrays. After spending $550 for literally the worst care imaginable. I spent the night keeping ice packs on my dog to bring her fever down. They SUCK!!! Take your money and more importantly your beloved pet ANYWHERE else!!! Beware of this scam vet clinic.

I want to start by saying an emergency veterinary clinic is expensive but that’s what comes with the “convenience “ of when an emergency occurs. (Usually 3am on a Sunday).. But I wanted to thank the team, My cat Johnny cashew came in for “acting suspiciously weird “.
He was just not his self and it lead to 2 emergency visits at VCA and IV/ urethra catheterization.
Most of the team was absolutely amazing. There were a few interactions that were less than desirable but let’s face it was a stressful situation. I want to give the highest praise to a few team members though, I am mentioning them because they went beyond the call of “Duty” and treated as it was.. A patient that needed help. Thank you Dr Green, Dr. Foster and Thomas. (And the vet techs that were on his rotation, I am so sorry I wish I had your names.)
You all absolutely helped save Johnny Cashews life. He is currently recovering from PU surgery so fingers crossed…. I will never be in or calling to “check his status “ all hours of the night. I am sure you were all exhausted but thank you for handling my kitty’s emergency and being kind to a “Crazy lady”.

Ive been here a few times in my life, once for my chinchillas eye and many times for other criters at my work, but I'm so thankful we went here to say goodbye to our pup Squire. We called all local emergency vets around and VCA has the most affordable option for euthanization. He was 17/18 years old and ended up having a seizure that night. Dr.Foster helped us make a really tough and went over what was going on before hand and discussed what are options would be. What resonates with me most she asked "do you think he is happy?" After weeks of not wanting to eat, not moving as much, using diapers and now this. She helped me and my mother make a really really tough decision. They brought us into a special room that I would call their goodbye room. The only thing I wished was if they asked us if we wanted to do paw print, even though it showed on the poster it was $30(?I think) to do one, it would have been nice as both vets I've been to, VEG and Brook-falls, did paw prints for free of under $7.I think we would have still wanted one.
Other than that, they were a tad busy. They gave the first sleeping med shot, while I do wish even though we spent that time in the room saying our goodbyes, after the first shot, I do wish we would have had a little bit more minutes to be alone with him being sleepy, but she did do the 2nd shot 30 seconds after the first, listened for a heart beat and he was gone. We spent a little extra time alone with him after his passing just to collect our feelings and we decided instead of cremation, that we would take him home so we could do his footprints there and a burial. But again I couldn't stress how compassionate Dr.Foster and the team at the front desk was. They helped us during this incredibly horrible and difficult difficult time. Thank you for all that you guys do, even when making hard decisions everyday, Dr.Foster and the team made sure to show a lot of compassion during this time of grieving.
