The veterinarians here care about your pets. We go here to get my pets vaccinations and if they are sick. The prices are not high. I can count on them to take care of my pet

We rescued our beloved Chunks from the streets and since then Dr Shim has been taking good care of him, he recommended to run some tests and we found out he is FVI positive. Thanks to Dr. Shim we can provide Chunks a good quality of life. I’ll recommend Alton Pet Clinic to everyone.

This is my favorite vet office I have ever been to. The staff here actually care about the animals and not just money, they work with the animal owners to make sure that the animal receives the best care at the best price.

My dog have a cancerous tumor, and I’ve been looking for the Vet to have surgery since I am not happy with my vet.. Visit to the Alton Main Animal Hospital today for surgery was awesome. I was very satisfied with the result. I really like Dr. Sim and his staff!! Dr. Sim is very kind, friendly and helpful. I look forward to returning again in the future!! Highly recommend this veterinary clinic!!!


The Dr. Is amazing, he is very effective, nice, and shows that he truly loves and cares for your pet. I always take my dog with this vet. My chihuahua is 3lbs and 7 years old, she had tumors on her belly and the Dr. put her down for surgery and thankfully everything went amazing. Their staff members are very nice and efficient.
