What a wonderful vet. So glad to have found him and his staff.

– Deb S.

Best vet in Livingston area! Always kind and compassionate to our pets and us.

– Tom M.

Dr. McCormick and his entire staff provide the absolute best care for furry babies. I have never met a veterinarian + team who demonstrate more compassion and loving care, not to mention the level of knowledge they have. Dr. McCormick will spend ample time answering all questions and explaining everything thoroughly. He clearly loves his job and the animals and stays up to date on all the latest developments and studies in the veterinary field. I will trust my sweet Riley with nobody else than this amazing team.

Dr. McCormick has been so great with the care of our dog Lucy. We have had some health problems that we aren’t even sure what they are, and he has been so awesome. We were on vacation and had my in-laws minding the dogs and Lucy had to go back into the vets and Dr. McCormick and his family treating Lucy as she was one of their own. We will not be going anywhere else.

Trevor McCormick is a good and caring man and vet. He came out to our house at 9:30 at night to help us end our beloved Jake’s suffering after a stroke. He had extended Jake’s life by about 5-6 years, but the diabetes finally won out. I can’t thank him enough. And, can’t wait until the new clinic is open! Cami and the whole staff are gentle and really love the animals. Can’t go wrong here, folks!

– Jerri M.

Dr. McCormick, Courtney, Kami and Sammy, are all wonderful people and each of them will go above and beyond for our pets. Trevor gets down on the floor with my dogs to make them comfortable rather than putting them on the metal table. My dogs love him and aren’t scared when we pull up to the building! They always manage to get us in quickly even when they are fully booked. These guys are great.

– Lauren S.

Dr. McCormick is not only extremely knowledgeable, but he has that gentle and calming presence around animals. All my dogs trust him instinctively. Thank you so much for providing a non-stressful environment for my babies. You ARE one in a million.

If ever anyone found their calling it is Trevor McCormick… my buddy Bob Marley gives a big paws up and I concur wholeheartedly!

– Molly J.

Dr. McCormick and his staff are amazing with our all our fur babies. They are the most compassionate and caring crew we have ever had the pleasure of vetting with. Our fur babies will not go anywhere else. They are the absolute best!

– Dc Mt.

Dr. McCormick, his family and staff have been exceptional! From routine visits to 1:00 a.m. emergency, our five pets have always been well cared for, for the last 10 plus years. Thanks, Doc! Xo Bear, Buddha, Moneypenny, Musashi, Mayhem. (Hey You & Kyra)
