Meet Cinderella

When you visit our clinic, you’ll meet our helpful office cat (and recurring employee of the month), Cinderella, who is always eager to greet newcomers and returning patients! It’s not uncommon to find her walking around the hallways, checking on patients, and making sure your pet feels like part of our family.

Why Animal Families Choose Us

“Dr. Thompson is very likely the best vet in Cheyenne, WY. He is amazing with his patients and their people… The staff is friendly and helpful, greeting you upon arrival and treating every customer as if you’re the only one they have. Zero complaints, all compliments!”

‒ Stephanie P.

“I absolutely LOVE this clinic. I have been going there for years. I have one pet that requires very special treatment, and they have gone out of their way to keep him healthy and pain-free… Thank you guys for everything you do for me and my Yorkie family. You are greatly appreciated.”

‒ Shelley A.

“Such a great clinic. The staff is extremely kind and gentle with the animals… Dr. Thompson was very clear with everything and extremely patient and caring. My other dogs will be going here from now on for their regular appointments.”

‒ Allen C.

“We cannot recommend Tri-State Veterinary Clinic enough. After having a poor experience at a local clinic, we sought out Dr. Thompson for a second opinion. It is very evident that he & his staff prioritize the well-being of their patients. Dr. Thompson is thorough, professional, and very kind… Highly recommend!”

‒ Margaret G.

“Been our vet for 19 years! It is obvious he [Dr. Thompson] loves the animals in his care. Patient and gentle with our crazy labs. He takes the time to answer all questions, and no one could have been more compassionate when it was time to help us say goodbye to our beautiful dogs.”

‒ Donna P.

“I had a very sick pup when I got home from work and I called them and they said to bring him right in and they would work him in. I know how difficult that is sometimes and they were very accommodating and I so appreciate that!”

– Robin H.

“Tri State Veterinary clinic was able to squeeze me in for a same day appointment when my own vet could not. They took my cat’s advanced age and my preferences into consideration when suggesting treatment options.”

– Tibeca Y.
