"Dr. Lan is amazing, compassionate and kind to the animals and his vet tech Nicole was so patient and caring with my shy Frenchie. They are very transparent about pricing and ask you if you're okay with something before they do it. Unlike other vet offices. They give you an estimate and make sure that you are okay with all the prices and communicate everything very clearly. I absolutely recommend and very affordable prices."
"My dog had a broken nail he was in pain. The doctor and the girls were very nice 👍 my dog got treated and got antibiotics. The awesome thing was that I did not make an appointment it was just a walk-in and fast. Thank you for helping me in a short time!! My dog feels a lot better ❤️🙏"
"The staff is super friendly. The receptionist is always super helpful. Even with my 5 billion questions. The techs are both so caring and you can see they are pet mommas. The doctor is extremely gentle and sweet. I cannot say enough good things."
"The dr doesn't say much but his knowledge is clear. He fixed my poor doggy. Staff is friendly and professional. The service is great and very affordable. Definitely will bring my fur baby back to dr Lan."
