What Our Clients Are Saying


Jenny F.

Very kind, competent staff. Beautiful, clean facility. We feel fortunate to have a veterinary medical practice in Janesville again. Driving to Reno for services is often not practical or possible. We appreciate the telephone messaging and texting options that keep us informed. Thank you, Thompson Peak, for keeping our 2 grrlz healthy and happy.

Took my dying kitty to them, they didn’t even hesitate to help her (lassen vet just kicked us out without looking at my kitty first). The vet was very efficient and told us everything ahead so we wouldn’t be surprised with the $ at the end. Unfortunately, life took my kitty that day. They offered us a the best cremation options they had, I was expecting for this visit to be around 1k. Services + cremation were only $500 (we chose private cremation too) The vet and the whole staff was crying with us when I lost my Pixie, they sent us a beautiful card in the mail a week later. So thoughtful and kind, they did everything they could during our emergency and I’ll always be thankful for them.

I had 3 cats spayed and a cat neutered within the past few months! The staff at Thompson Peak Vet were very knowledgable and caring, they even called post surgery to assure me that my pets made it through surgery safely:) I feel like they love my pets as much as I do! I'm so relieved to have a vet i can trust!

This is the place to take your pet for quality care and people that clearly know their stuff and genuinely care. The waiting area is very cozy but spacious at the same time. Just really comfortable. Really nice people up front and on the phones. My dog had an abscess and they were able to get her in for dental surgery only a couple days later. They fixed my girl up and she has healed nicely. Just really pleased. Thank you.

Matthew J.

Took our family pet to Thompson Peak veterinary clinic and was very pleasantly surprised. They keep a full appointment book but are always willing to talk and staff are very responsive to questions about the health well-being of animals. Both the veterinarian and the veterinary assistant were very gentle and understanding and were able to treat the needs of our family pet!
